In C#, MathF.Log10(Single) is a MathF class method. It is used to return the base 10 logarithm of a specified number.
Syntax: public static float Log10 (float x);
Here, x is the specified number whose logarithm to be calculated and its type is System.Single.
Return Value: It returns the logarithm of val(base 10 log of val) and its type is System.Single.
Note: Parameter x is always specified as a base 10 number. The return value is depend on the argument passed. Below are some cases:
- If the argument is positive then method will return the natural logarithm or log10(val).
- If the argument is zero, then the result is NegativeInfinity.
- If the argument is Negative(less than zero) or equal to NaN, then the result is NaN.
- If the argument is PositiveInfinity, then the result is PositiveInfinity.
- If the argument is NegativeInfinity, then the result is NaN.
Example:
using System;
class Geeks {
public static void Main(String[] args)
{
float a = 9.887f;
float b = 0f;
float c = -4.45f;
float nan = Single.NaN;
float positiveInfinity = Single.PositiveInfinity;
float negativeInfinity = Single.NegativeInfinity;
Console.WriteLine(MathF.Log10(a));
Console.WriteLine(MathF.Log10(b));
Console.WriteLine(MathF.Log10(c));
Console.WriteLine(MathF.Log10(nan));
Console.WriteLine(MathF.Log10(positiveInfinity));
Console.WriteLine(MathF.Log10(negativeInfinity));
}
}
