just a simple query, not necessarily related to netbsd although it
might be interesting to find out...
does anyone out there who compiles and runs this program
#include <stdio.h>
int main(void)
{
int dividend,divisor,quotient,remainder;
dividend=-3;
divisor=-2;
quotient=dividend/divisor;
remainder=dividend%divisor;
printf("%d %d %d %d\n",dividend,divisor,quotient,remainder);
}
not get
-3 -2 1 -1
as output? any system at all, any os at all...i'm trying to find something
somewhere that does not. the reason stems from the k&r book's definition
on what the quotient and remainder will be from integer arithmetic. see
section A7.6, paragraph 4:
".... If both operands are non-negative, then the remainder is non-
negative and smaller than the divisor; if not, it is guaranteed only
that the absolute value of the remainder is smaller than the absolute
value of the divisor."
if anyone finds such a machine, please let me know...?
