How to get proper modulus in java.

Question

-3 % 5 should return 2
Java returns -3 instead. This is wrong since the sign should equal the divisor's.
Is there some builtin method/library in java which returns the correct value?
I know this can be fixed by using an if/while statement to check whether the number is negative, but I don't want that.

Answer 1

    public static void main(String[] args) throws Exception {
        System.out.println(mod(-3, 100));
        System.out.println(mod2(-3, 100));
    public static int mod(int a, int b) {
        return Math.abs(b) % Math.abs(a);
    public static int mod2(int a, int b) {
        return ((a%b)+b)%b;
    }Mine print outs 1
Yours prints out 97
How is your method giving the modulus?
