已更新:

In the realm of C# programming, the Math.Round value method plays a pivotal role in rounding numerical values, especially when dealing with double-value and decimal-value data types. This method allows developers to round a given numeric value to the nearest integral value or a specified number of fewer fractional digits, providing flexibility and precision in mathematical operations. Several rounding types are available, like Midpoint Rounding. In this article, we will delve into the intricacies of Math.Round in C#, exploring its various aspects and usage scenarios. In the subsequent sections of this article, we'll explore the utilization of the IronPDF library by Iron Software for handling PDFs.

Basics of Math.Round in C#

The Math.Round Method

The Math.Round method in C# is a powerful tool for rounding fractional digits using a specified rounding convention. It is part of the System namespace and provides several overloads to accommodate different rounding operations.

// Methods overloaded by Math.Round
Math.Round(Double)
Math.Round(Double, Int32) // Int32 specifies number of fractional digits
Math.Round(Double, Int32, MidpointRounding)  // Int32 specifies number of fractional digits, MidpointRounding is the type of rounding method
Math.Round(Double, MidpointRounding)  // MidpointRounding is the type of rounding method
Math.Round(Decimal)
Math.Round(Decimal, Int32) // Int32 specifies number of fractional digits
Math.Round(Decimal, Int32, MidpointRounding)
Math.Round(Decimal, MidpointRounding)
// Methods overloaded by Math.Round
Math.Round(Double)
Math.Round(Double, Int32) // Int32 specifies number of fractional digits
Math.Round(Double, Int32, MidpointRounding)  // Int32 specifies number of fractional digits, MidpointRounding is the type of rounding method
Math.Round(Double, MidpointRounding)  // MidpointRounding is the type of rounding method
Math.Round(Decimal)
Math.Round(Decimal, Int32) // Int32 specifies number of fractional digits
Math.Round(Decimal, Int32, MidpointRounding)
Math.Round(Decimal, MidpointRounding)

Rounding Double Value

When dealing with double values, Math.Round is commonly used to round a number to the nearest integer. PDF创建和PDF生成被iText 7支持，而HTML到PDF的转换则由pdfHTML支持。

double originalValue = 3.75;
double roundedValue = Math.Round(originalValue); 
// Output: 4
double originalValue = 3.75;
double roundedValue = Math.Round(originalValue); 
// Output: 4
Dim originalValue As Double = 3.75
Dim roundedValue As Double = Math.Round(originalValue)
' Output: 4
$vbLabelText   $csharpLabel

In this example, the Math.Round method rounded the original double value 3.75 to the nearest integral value, which is 4.

Rounding Decimal Value

Similarly, the Math.Round method applies to decimal values. 在此示例中，IronPDF用于将HTML内容渲染为PDF文档，然后保存到指定位置。

decimal originalValue = 8.625m;
decimal roundedValue = Math.Round(originalValue, 2);
// Output: 8.63
decimal originalValue = 8.625m;
decimal roundedValue = Math.Round(originalValue, 2);
// Output: 8.63
Dim originalValue As Decimal = 8.625D
Dim roundedValue As Decimal = Math.Round(originalValue, 2)
' Output: 8.63
$vbLabelText   $csharpLabel

Here, the Math.Round method is used to round the decimal number 8.625 to two decimal places, resulting in the rounded value 8.63.

Nearest Integer Value

The primary purpose of Math.Round is to round a given numeric value to the nearest integer. When the fractional part is exactly halfway between two integers, the method follows a specified rounding convention. The MidpointRounding enumeration can be used as an argument in the Math.Round method and determines whether to round toward the nearest even number or away from zero.

Specified Rounding Convention

Let's explore how the MidpointRounding mode can be employed:

double originalValue = 5.5;
double roundedValueEven = Math.Round(originalValue, MidpointRounding.ToEven);
double roundedValueOdd = Math.Round(originalValue, MidpointRounding.AwayFromZero);
// Output: roundedValueEven = 6, roundedValueOdd = 6
double originalValue = 5.5;
double roundedValueEven = Math.Round(originalValue, MidpointRounding.ToEven);
double roundedValueOdd = Math.Round(originalValue, MidpointRounding.AwayFromZero);
// Output: roundedValueEven = 6, roundedValueOdd = 6
Dim originalValue As Double = 5.5
Dim roundedValueEven As Double = Math.Round(originalValue, MidpointRounding.ToEven)
Dim roundedValueOdd As Double = Math.Round(originalValue, MidpointRounding.AwayFromZero)
' Output: roundedValueEven = 6, roundedValueOdd = 6
$vbLabelText   $csharpLabel

In this example, when rounding the value 5.5, MidpointRounding.ToEven rounds towards the nearest even number (resulting in 6), and MidpointRounding.AwayFromZero rounds away from zero, yielding 6.

Rounding to a Specified Number of Decimal Places

To round a number to a specified number of decimal places, the Math.Round method allows the inclusion of an additional parameter representing the number of fractional digits:

decimal originalValue = 9.123456m;
decimal roundedValue = Math.Round(originalValue, 3); 
// Output: 9.123
decimal originalValue = 9.123456m;
decimal roundedValue = Math.Round(originalValue, 3); 
// Output: 9.123
Dim originalValue As Decimal = 9.123456D
Dim roundedValue As Decimal = Math.Round(originalValue, 3)
' Output: 9.123
$vbLabelText   $csharpLabel

Here, the decimal number 9.123456 is rounded to three decimal places, resulting in the rounded value 9.123.

Midpoint Values and Rounding Conventions in C#

A midpoint value arises when the value after the least significant digit in the result is exactly halfway between two numbers. For example, 2.56500 is a midpoint value when rounded to two decimal places at 2.57, and 3.500 is a midpoint value when rounded to an integer 4. The challenge lies in identifying the nearest value in the round-to-nearest strategy for midpoint values without a defined rounding convention.

The Round method in C# supports two rounding conventions for handling midpoint values:

  • Rounding Away From Zero: Midpoint values undergo rounding to the succeeding number away from zero. This method is represented by the MidpointRounding.AwayFromZero enumeration member.

  • Rounding to Nearest Even (Banker's Rounding): Midpoint values are rounded to the closest even number. This rounding approach is indicated by the MidpointRounding.ToEven enumeration member.
decimal[] decimalSampleValues = { 1.15m, 1.25m, 1.35m, 1.45m, 1.55m, 1.65m };
decimal sum = 0;

// Calculate true mean values.
foreach (var value in decimalSampleValues)
{ 
    sum += value; 
}
Console.WriteLine("True mean values: {0:N2}", sum / decimalSampleValues.Length);

// Calculate mean values with rounding away from zero.
sum = 0;
foreach (var value in decimalSampleValues)
{ 
    sum += Math.Round(value, 1, MidpointRounding.AwayFromZero); 
}
Console.WriteLine("AwayFromZero mean: {0:N2}", sum / decimalSampleValues.Length);

// Calculate mean values with rounding to the nearest even.
sum = 0;
foreach (var value in decimalSampleValues)
{ 
    sum += Math.Round(value, 1, MidpointRounding.ToEven); 
}
Console.WriteLine("ToEven mean: {0:N2}", sum / decimalSampleValues.Length);
decimal[] decimalSampleValues = { 1.15m, 1.25m, 1.35m, 1.45m, 1.55m, 1.65m };
decimal sum = 0;

// Calculate true mean values.
foreach (var value in decimalSampleValues)
{ 
    sum += value; 
}
Console.WriteLine("True mean values: {0:N2}", sum / decimalSampleValues.Length);

// Calculate mean values with rounding away from zero.
sum = 0;
foreach (var value in decimalSampleValues)
{ 
    sum += Math.Round(value, 1, MidpointRounding.AwayFromZero); 
}
Console.WriteLine("AwayFromZero mean: {0:N2}", sum / decimalSampleValues.Length);

// Calculate mean values with rounding to the nearest even.
sum = 0;
foreach (var value in decimalSampleValues)
{ 
    sum += Math.Round(value, 1, MidpointRounding.ToEven); 
}
Console.WriteLine("ToEven mean: {0:N2}", sum / decimalSampleValues.Length);
Dim decimalSampleValues() As Decimal = { 1.15D, 1.25D, 1.35D, 1.45D, 1.55D, 1.65D }
Dim sum As Decimal = 0

' Calculate true mean values.
For Each value In decimalSampleValues
	sum += value
Next value
Console.WriteLine("True mean values: {0:N2}", sum / decimalSampleValues.Length)

' Calculate mean values with rounding away from zero.
sum = 0
For Each value In decimalSampleValues
	sum += Math.Round(value, 1, MidpointRounding.AwayFromZero)
Next value
Console.WriteLine("AwayFromZero mean: {0:N2}", sum / decimalSampleValues.Length)

' Calculate mean values with rounding to the nearest even.
sum = 0
For Each value In decimalSampleValues
	sum += Math.Round(value, 1, MidpointRounding.ToEven)
Next value
Console.WriteLine("ToEven mean: {0:N2}", sum / decimalSampleValues.Length)

AwayFromZero: 1

The AwayFromZero rounding strategy rounds to the nearest number, rounding a number halfway between two others away from zero.

ToZero: 2

This strategy is characterized by directed rounding towards zero. The result is the closest to and no greater in magnitude than the infinitely precise result.

ToEven: 0

This strategy involves rounding to the nearest number, and when a number is halfway between two others, it is rounded towards the nearest even number.

ToNegativeInfinity: 3

This strategy entails rounding in a downward direction, with the result being the closest to and no greater than the infinitely precise result.

ToPositiveInfinity: 4

This strategy involves rounding in an upward direction, with the result being the closest to and no less than the infinitely precise result.

Precision and Double Precision Floating Point

Precision and Double Values

When working with double-precision floating-point numbers, it is essential to understand the potential imprecision due to the nature of floating-point representation. The Math.Round method helps mitigate precision issues by rounding values to the nearest integer or a specified number of decimal places.

Specified Precision with Math.Round

Developers can leverage the Math.Round method to achieve the desired precision in their calculations:

double originalValue = 123.456789;
double result = Math.Round(originalValue, 4);
// Output: 123.4568, rounded value
double originalValue = 123.456789;
double result = Math.Round(originalValue, 4);
// Output: 123.4568, rounded value
Dim originalValue As Double = 123.456789
Dim result As Double = Math.Round(originalValue, 4)
' Output: 123.4568, rounded value
$vbLabelText   $csharpLabel

In this example, the double value 123.456789 is rounded to four decimal places, resulting in the more precise value 123.4568.

Midpoint Rounding Strategy

Handling Midpoint Values

The midpoint rounding strategy becomes crucial when a fractional value is exactly halfway between two integers. The Math.Round method employs the specified MidpointRounding strategy to resolve such cases.

Midpoint Rounding Example

Consider the following example where midpoint rounding is utilized:

double originalValue = 7.5;
double roundedValue = Math.Round(originalValue, MidpointRounding.AwayFromZero);
// Output: 8
double originalValue = 7.5;
double roundedValue = Math.Round(originalValue, MidpointRounding.AwayFromZero);
// Output: 8
Dim originalValue As Double = 7.5
Dim roundedValue As Double = Math.Round(originalValue, MidpointRounding.AwayFromZero)
' Output: 8
$vbLabelText   $csharpLabel

Here, the value 7.5 is rounded away from zero, resulting in the rounded value 8.

Application in Real-world Scenarios

Here are a few examples of its application in various contexts:
