Math class methods in C#
The System.Math class in C# provides methods are properties to perform mathematical operations, trigonometric, logarithmic calculations, etc.
Some of its methods include −
| Sr.No | Method & Description |
|---|---|
| 1 | Abs(Decimal) Returns the absolute value of a Decimal number. |
| 2 | Abs(Double) Returns the absolute value of a double-precision floating-point number. |
| 3 | Abs(Int16) Returns the absolute value of a 16-bit signed integer. |
| 4 | Abs(Int32) Returns the absolute value of a 32-bit signed integer. |
| 5 | Abs(Int64) Returns the absolute value of a 64-bit signed integer. |
| 6 | Abs(SByte) Returns the absolute value of an 8-bit signed integer. |
| 7 | Abs(Single) Returns the absolute value of a single-precision floating-point number. |
| 8 | Acos(Double) Returns the angle whose cosine is the specified number. |
| 9 | Asin(Double) Returns the angle whose sine is the specified number. |
| 10 | Atan(Double) Returns the angle whose tangent is the specified number. |
For all the methods, refer MSDN
Let us see an example to get the absolute value −
Example
using System;
class Program {
static void Main() {
int val1 = 50;
int val2 = -150;
Console.WriteLine("Before...");
Console.WriteLine(val1);
Console.WriteLine(val2);
int abs1 = Math.Abs(val1);
int abs2 = Math.Abs(val2);
Console.WriteLine("After...");
Console.WriteLine(abs1);
Console.WriteLine(abs2);
}
}
