Wire Modulo Node giving incorrect value for negative inputs

[samTrolland]

It looks like the Wire node 'Modulo' gives incorrect values for negative numerator inputs.

Example according to Wolfram Alpha:
11 mod 7 = 4
-11 mod 7 = 3

In Wire:
11 mod 7 = 4 (correct)
-11 mod 7 = -4 (incorrect)

The correct Modulo result for negative inputs can be achieved in Wire using a few extra logic nodes:

If the Modulo Result is less than 0 then add the denominator to the result.

-11 mod 7 = 3 (correct)

11 mod 7 = 4 (correct)

There are some ways to do mod, looks like wolfram does a different one than Wire.
If you try the same in Processing you get the same result as in Wire.
