Dear colleagues,
one of my friends has raisen very strange issue regarding gcc rounding:
[EMAIL PROTECTED]:/tmp/tsostik> uname -r 4.10-STABLE [EMAIL PROTECTED]:/tmp/tsostik> gcc -v Using builtin specs. gcc version 2.95.4 20020320 [FreeBSD]
[EMAIL PROTECTED]:/tmp/tsostik> cat x.c
#include <stdio.h>
int main ()
{
float a;
for(a=0.01;a<=0.1; a+=0.01)
printf("%f %.3f %d\n", a*100, a*100, (int)(a*100));
I believe this should more correct:
printf ("%f %.3f %d\n", a*100, a*100, (int)(a*100+.5));rik
return 0; } [EMAIL PROTECTED]:/tmp/tsostik> cc x.c [EMAIL PROTECTED]:/tmp/tsostik> ./a.out 1.000000 1.000 0 2.000000 2.000 1 3.000000 3.000 2 4.000000 4.000 3 5.000000 5.000 5 6.000000 6.000 6 7.000000 7.000 7 8.000000 8.000 7 9.000000 9.000 8 9.999999 10.000 9
Any comments?
