Re: Problem with lroundf()

Problem with lroundf()

Hi all, I think the following exhibits a bug in the lroundf() routine: $ cat a.c #include #include int main (void) { printf ("%d\n", (int) lroundf(0.7)); } $ gcc a.c && ./a.exe 0 The result of lroundf(0.7) should be 1, not 0. If lround() is used instead of lroundf(), then it's working OK.
