Subject: bug in float on Pentium
Date: Fri, 13 Apr 2001 19:23:24 -0400	[thread overview]
Message-ID: <3AD78A6C.F0F3CF5A@mindspring.com> (raw)

Not sure but I think I found a NEW bug.

I know that there have been some issues with pentiums and floating point
arrithmatic, but this takes the cake...

Linux Lserver.org 2.2.18 #43 SMP Fri Mar 9 14:19:41 EST 2001 i586
unknown

>kgcc --version
egcs-2.91.66

RH 6.2.x / 7.0

try this program

#include <stdio.h>

int main() {

    char tmpx[100];
 char tmpy[100];

 double x = 5483.99;
 float y = 5483.99;

    sprintf (tmpx, "%f",x );
    sprintf (tmpy, "%f",y );

 printf ("%s\n%s\n", tmpx, tmpy);
 return 0;
}


I am getting the following as output

joeja@Lserver$ ./testf
5483.990000
5483.990234


what is with the .990234??  it should be .990000

any ideas on this??
