System: NetBSD polaris 1.3.2 NetBSD 1.3.2 (POLARIS) #1: Fri Nov 6 07:41:34 MST 1998 root@:/usr/src/sys/arch/i386/compile/POLARIS i386


>Description:
Ran a test program on i386 and alpha, to divide by zero, and spit out the
results, hoping to find out why perl dumps core when dividing by zero on
alpha, and found:

(i386)
[/home/garbled] polaris# ./float
i: Inf
j: Inf

(alpha)
giauzar# ./float 
i: Inf
j: 340282346638528859811704183484516925440.000000

	
>How-To-Repeat:
#include <stdio.h>

main() {

double i;
float j;

i = 12.0 / 0;
printf("i: %f\n", i);
j = 12.0 / 0;
printf("j: %f\n", j);

}
	
>Fix:
Not sure.. is this even a bug?  Is "Inf" being promoted incorrectly?
