MathF.Sign() Method in C# with Examples
The MathF.Sign() method in C# returns an integer specifying the sign of the number.
Syntax
Following is the syntax −
public static int Sign (float val);
Above, Val is the floating-point number whose sign is to be calculated.
The return value is 0 if Val is zero. It’s -1 if the value is less than zero and 1 if the value is greater than zero.
Example
Let us now see an example to implement the MathF.Sign() method −
using System;
public class Demo {
public static void Main(){
float val1 = 10.23898f;
float val2 = -20.878788f;
Console.WriteLine("MathF.Sign(val1) = "+MathF.Sign(val1));
Console.WriteLine("MathF.Sign(val2) = "+MathF.Sign(val2));
}
}Output
This will produce the following output −
MathF.Sign(val1) = 1 MathF.Sign(val2) = -1
Example
Let us now see another example to implement the MathF.Sign() method −
using System;
public class Demo {
public static void Main(){
float val1 = 0.00f;
float val2 = -10.6735f;
Console.WriteLine("MathF.Sign(val1) = "+MathF.Sign(val1));
Console.WriteLine("MathF.Sign(val2) = "+MathF.Sign(val2));
}
}Output
This will produce the following output −
MathF.Sign(val1) = 0 MathF.Sign(val2) = -1
