C# has a built-in Math class that provides useful mathematical functions and operations. This class has the Log10() function, which is used to compute the base 10 logarithm of a specified number.
public static double Log10 (double value);
value: This is of the Double type and represents the input value for which we have to find Log10(). Its range is all double numbers.Double: This returns a positive Double number representing the base 10 log of the value.
NaN: This returns an input of negative or NaN in value.
PositiveInfinity: This returns an input of PositiveInfinity in value.
NegativeInfinity: This returns an input of 0 in value.
valueis a base 10 number.
