printf in glibc rounds, I think you should read something about rounding.
The default rounding mode (and the only one actually implemented for printf) is
round to even. http://www.lmgtfy.com/?q=round+to+even
So
#include <stdio.h>
int
main (void)
{
printf ("%.2f\n", 5798.12500);
printf ("%.2f\n", 5798.87500);
return 0;
}
printing
5798.12
5798.88
is correct.
