Hy netlanders,
I have SCO UNIX Version 3.2.0 with Development Kit.
The atof()-function does not work proberly. Is there a work-a-round
of this problem?
My test-programm:
#include <stdio.h>
#include <math.h>
main()
{
double f;
f=atof("123.23");
printf("F: %f \n",f);
}

Unfortunately you don't say in what way it doesn't work. One possibility is that it is not declared in the .h files you include - try adding extern double atof(); to your program. -- Richard -- Richard Tobin, JANET: R.Tobin@uk.ac.ed AI Applications Institute, ARPA: R.Tobin%uk.ac.ed@nsfnet-relay.ac.uk Edinburgh University.

The SCU Unix System V/386 Development System Programmer's Reference manual manual page for ATOF(S) gives the following syntax description: #include <math.h> double atof(nptr) char *nptr; The entry for "atoi" and "atol" give the correct include file, which is as Mr. van der Pol states, "stdlib.h." Mr. Basien did everything correctly according to the manual, but was simply bitten by a documentation error. -- Jack Cloninger, TeqSoft, 112 US Highway 1, Tequesta, FL 33469 B-) ...uunet!comtst!teqsoft!jmc Phone: 407-747-7163 Fax: 407-747-0354
