ATOF(3)                    Library Functions Manual                    ATOF(3)



NAME
       atof, atoi, atol - convert ASCII to numbers

SYNOPSIS
       double atof(nptr)
       char *nptr;

       int atoi(nptr)
       char *nptr;

       long atol(nptr)
       char *nptr;

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

       Atof recognizes an optional string of tabs and 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 tabs and spaces, then an
       optional sign, then a string of digits.

SEE ALSO
       scanf(3)

BUGS
       There are no provisions for overflow.
