NAME
       atof, atoi, atol - convert ASCII to numbers

SYNOPSIS
       double atof(nptr)
       char *nptr;

       atoi(nptr)
       char *nptr;

       long atol(nptr)
       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 dig-
       its  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
       scanf(3S)

BUGS
       There are no provisions for overflow.
