MathF.Log10() Method in C# with Examples
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:
// C# program to demonstrate working // of MathF.Log10(Single) method using System; class Beginner { // Main Method public static void Main(String[] args) { // float values whose logarithm // to be calculated float a = 9.887f; float b = 0f; float c = -4.45f; float nan = Single.NaN; float positiveInfinity = Single.PositiveInfinity; float negativeInfinity = Single.NegativeInfinity; // Input is positive number so output // will be logarithm of number Console.WriteLine(MathF.Log10(a)); // positive zero as argument, so output // will be -Infinity Console.WriteLine(MathF.Log10(b)); // Input is negative number so output // will be NaN Console.WriteLine(MathF.Log10(c)); // Input is NaN so output // will be NaN Console.WriteLine(MathF.Log10(nan)); // Input is PositiveInfinity so output // will be Infinity Console.WriteLine(MathF.Log10(positiveInfinity)); // Input is NegativeInfinity so output // will be NaN Console.WriteLine(MathF.Log10(negativeInfinity)); } } |
Output:
0.9950646 -Infinity NaN NaN Infinity NaN
