C# | Math.Log10() Method
In C#, Math.Log10() is a Math class method. It is used to return the base 10 logarithm of a specified number.
public static double Log10(double val)
val: It is the specified number whose logarithm to be calculated and its type is System.Double.
Return Value: It returns the logarithm of val(base 10 log of val) and its type is System.Double.
Note: Parameter val 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.
