When printf "%g" with trailing 0 number, decial point be printed.
C lang's printf function doesn't print decimal point if only trailing 0s. But GHC does.
Prelude Text.Printf> :m + Text.Printf
Prelude Text.Printf> printf "%g\n" 2.0
2.0#include <stdio.h>
int main() {
printf("%g\n", 2.0);
return 0;
}
// output: 2Is this bug? Should printf be compatible with C?
