NAME
       log10, log10f, log10l -	base-10 logarithmic function

SYNOPSIS
       #include <math.h>

       double log10(double x);
       float log10f(float x);
       long double log10l(long double x);

       Link with -lm.

       log10f(), log10l():
	   _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||

	   or cc -std=c99

DESCRIPTION
       The log10() function returns the base 10 logarithm of x.

RETURN VALUE
       On success, these functions return the base 10 logarithm of x.

       For special cases, including where x is 0, 1,  negative,	 infinity,  or
       NaN, see log(3).

ERRORS
       See  math_error(7) for information on how to determine whether an error
