NAME

       atof, atoi, atol - convert ASCII 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 unrecog-
       nized 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.

SEE ALSO

       strtol(3), strtod(3), scanf(3).

BUGS

       There are no provisions for overflow.

NAME

       atof - convert a string to a double

SYNOPSIS

       #include <stdlib.h>

       double atof(const char *nptr);

DESCRIPTION

       The atof() function converts the initial portion of the string pointed to by nptr to double.  The behavior is the same as

	   strtod(nptr, NULL);

       except that atof() does not detect errors.

RETURN VALUE

       The converted value.
