NAME
       atof - convert a string to a double

SYNOPSIS
       #include <stdlib.h>

       double atof(const char *nptr);

DESCRIPTION
       The atof() function converts the initial portion of the string pointed
       to by nptr to double.  The behavior is the same as

           strtod(nptr, NULL);

       except that atof() does not detect errors.

RETURN VALUE
       The converted value.
