ATOF(3)                 GENIX 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  nptr  to  floating,
           integer,  and  long  integer representation respectively.  The first
           unrecognized 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.
