Package: gcc-4.4
Version: 4.4.4-11
Severity: normal
Hello,
The present bugreport is a followup to #593193 and a regression wrt
4.3.
Steps to reproduce:
(sid)smetana:~/gcc-4.4/gmp-ecm-6.3$ cat bug.c
#include <stdio.h>
int
main()
{
unsigned int t = 254733465;
float f;
f = (float) t;
printf ("t=%u f=%.0f\n", t, f);
}
(sid)smetana:~/gcc-4.4/gmp-ecm-6.3$ gcc-4.4 bug.c; ./a.out
t=254733465 f=482062944
(sid)smetana:~/gcc-4.4/gmp-ecm-6.3$ gcc-4.3 bug.c; ./a.out
t=254733465 f=254733472
The correct result is the second one, since the closest single precision
float (24-bit significand) from 254733465 is 254733472.
Many thanks to Lucas Nussbaum and Paul Zimmermann for working on this
bug.
Regards,
Laurent Fousse.
