ATOF(3)             UNIX Programmer's Manual              ATOF(3)

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 _n_p_t_r to
     floating, integer, and long integer representation respec-
     tively.  The first unrecognized character ends the string.

     _A_t_o_f recognizes an optional string of tabs and spaces, then
     an optional sign, then a string of digits optionally con-
     taining a decimal point, then an optional `e' or `E' fol-
     lowed by an optionally signed integer.

     _A_t_o_i and _a_t_o_l recognize an optional string of tabs and
     spaces, then an optional sign, then a string of digits.

SEE ALSO
     scanf(3S)

BUGS
     There are no provisions for overflow.
