NAME

       atof - convert a string to a double

LIBRARY

       Standard C library (libc, -lc)

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.
