NAME
       atof, atoi, atol - convert ASCII to numbers

SYNOPSIS
       #include <stdlib.h>

       double atof(const char *nptr)
       int atoi(const char *nptr)
       long atol(const char *nptr)

DESCRIPTION
       These functions convert a string pointed to by nptr to floating, integer, and long integer representation respectively.	The first unrecog-
       nized character ends the string.

       Atof recognizes an optional string of spaces, then an optional sign, then a string of digits optionally containing a decimal point, then an
       optional `e' or `E' followed by an optionally signed integer.

       Atoi and atol recognize an optional string of spaces, then an optional sign, then a string of digits.

SEE ALSO
       strtol(3), strtod(3), scanf(3).

BUGS
       There are no provisions for overflow.
