Hi!

I've just noticed some confusing behaviour when using the % operator on negative numbers in JSFX. The results seem to vary depending on whether you use variables or constants in the expression. Here's an example:

Code:

result1 = -301 % 100; // produces -1

a = -301; b = 100;
result2 = a % b;      // produces +1

It appears to do this same thing across a few different Reaper versions and system architectures that I've had a chance to try.
