C# 浮點數 (如何為開發人員運作)

float height = 5.8f;
float width = 3.14f;

Dim height As Single = 5.8F
Dim width As Single = 3.14F

float value = 5.678f;
float roundedValue = Math.Round(value, 2);   // Rounds to 2 decimal places: 5.68
float floorValue = Math.Floor(value);        // Rounds down: 5.0
float ceilingValue = Math.Ceiling(value);    // Rounds up: 6.0

Dim value As Single = 5.678F
Dim roundedValue As Single = Math.Round(value, 2) ' Rounds to 2 decimal places: 5.68
Dim floorValue As Single = Math.Floor(value) ' Rounds down: 5.0
Dim ceilingValue As Single = Math.Ceiling(value) ' Rounds up: 6.0
