NAME
       atof, atoi, atol - convert strings 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
       unrecognized 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.

RETURN VALUE
       Atof , atoi , and atol return the converted value.

BUGS
       There are no provisions for overflow.
