RoundCeil(0.002, -1) != 0.1

[milan-enclave]

When doing RoundCeiling operation to 0.002 with precision set to -1, we get 0 instead of 0.1.
However for RoundCeiling(1.002, -1) we get 1.1.

	var num apd.Decimal

	_, err = ctx.Quantize(&num, &num, -1)
	if err != nil {
		t.Fatal(err)
	}
	if num.String() != "0.1" {
		t.Errorf("Expected 0.1, got %s", num.String())
	}
