Wrong double -> int conversion when double is < 0
#include <stdio.h>
int
main()
{
// Ok if d >0
{
double d = 413.55;
long l = (long)d;
int i = (int)d;
printf("d=%f, i=%d (OK), l=%ld (OK)\n", d, i, l);
}
// BUG if d <0
{
double d = -413.55;
long l = (long)d;
int i = (int)d;
printf("d=%f, i=%d (BUG), l=%ld (BUG)\n", d, i, l);
}
}
jullien~/openlisp/src $ tcc foo.c && ./a.out
d=413.550000, i=414 (OK), l=414 (OK)
d=-413.550000, i=0 (BUG), l=0 (BUG)
