C# Numerische Typen (Wie es für Entwickler funktioniert)

Integer Data Types

Integer data types are utilized to store whole numbers and can be either signed (capable of holding both positive and negative numbers) or unsigned (capable of holding only positive numbers). Here's a breakdown of the integer types in C#:

Floating-Point Number Types

Floating-point types are used to store numbers with a decimal point. A floating-point number provides a much wider range of values than integer types, but with a trade-off in precision. Here are the floating-point types in C#:

Understanding Native Sized Integer Types

Native sized integer types are special types in C# that have a size that varies depending on the platform the code is running on. These are designed to provide the most efficient use of memory for storing integer values.

Converting Between Integer and Floating-Point Types

Depending on the use case, it’s important to use the correct data type in your code. In many cases, you may have a value of one type and need to use it as another type.

Implicit conversions happen automatically when the value to be converted will fit into the new data type without losing any information. For example, you can implicitly convert an int to a long, as a long can store the same value as an int.

Explicit conversions, also known as casting, are required when there's a risk of data loss. For example, converting a long to an int may result in data loss if the long's value is larger than what an int can hold.

To explicitly cast a value from one type to another, you can use the casting operator ():

long myLong = 5000L;
int myInt = (int)myLong; // This is an explicit cast from long to int.
                         // Be cautious if myLong > 2,147,483,647 as it may cause data loss.

long myLong = 5000L;
int myInt = (int)myLong; // This is an explicit cast from long to int.
                         // Be cautious if myLong > 2,147,483,647 as it may cause data loss.

Dim myLong As Long = 5000L
Dim myInt As Integer = CInt(myLong) ' This is an explicit cast from long to int.
						 ' Be cautious if myLong > 2,147,483,647 as it may cause data loss.

Be careful when casting, as it can lead to unexpected results if the value is outside the range of the target type.

Applying Numeric Types Using IronPDF

IronPDF is a lightweight .NET PDF library designed specifically with web developers in mind. It makes reading, writing, and manipulating PDF files a breeze, able to convert all kinds of file types into PDF content, and you can use it in your .NET projects for both desktop and web. The best part - it’s free to try out in a development environment.

Let’s take a look at implementing types in C# using IronPDF.

using IronPdf;

var htmlToPdf = new ChromePdfRenderer();
htmlToPdf.RenderingOptions.MarginTop = 50;    // Set top margin in points.
htmlToPdf.RenderingOptions.MarginBottom = 50; // Set bottom margin in points.

var document = htmlToPdf.RenderHtmlAsPdf("<h1>Numeric Types in C# with IronPDF</h1>");
document.SaveAs("C:\\numericTypes.pdf");       // Save the generated PDF to the specified path.

using IronPdf;

var htmlToPdf = new ChromePdfRenderer();
htmlToPdf.RenderingOptions.MarginTop = 50;    // Set top margin in points.
htmlToPdf.RenderingOptions.MarginBottom = 50; // Set bottom margin in points.

var document = htmlToPdf.RenderHtmlAsPdf("<h1>Numeric Types in C# with IronPDF</h1>");
document.SaveAs("C:\\numericTypes.pdf");       // Save the generated PDF to the specified path.

Imports IronPdf

Private htmlToPdf = New ChromePdfRenderer()
htmlToPdf.RenderingOptions.MarginTop = 50 ' Set top margin in points.
htmlToPdf.RenderingOptions.MarginBottom = 50 ' Set bottom margin in points.

Dim document = htmlToPdf.RenderHtmlAsPdf("<h1>Numeric Types in C# with IronPDF</h1>")
document.SaveAs("C:\numericTypes.pdf") ' Save the generated PDF to the specified path.

Conclusion

From basic calculations to customizing the layout of a generated PDF, number types are an important part of effective and efficient C# programming. They serve as the building blocks for data manipulation, algorithm design, and the creation of high-quality PDF documents.
