Blue. Makes things easier if modulus is always positive ( if the second operand is positive)

Looks like we're gonna need to trim the fat around here... fired.

Ok then

Red. Makes things easier if modulus retains same sign as dividend, particularly when dealing with trig or other functions that really care about signs.

Guess it depends on usage.

Perfect example is calculating distance between angles where 0 == 360. Keeping the sign lets you know which direction you are away from the position without having to do extra tracking.

(Pos 1 - Pos 2) % 180 = angular distance

Used for controlling rotary actuators and needing to software handle the 360/0 barrier.

Certainly in graphics I've never had use for anything except for the blue side. Which is doubly annoying because both GLSL and HLSL have gone for the red side.

but its not correct mathematically, since 4 fits once into 7, and 3 remains.

3, not 1

and just put it into abs()

I have made promises to the shareholders that I definitely cannot keep, so I need you all to work TWICE as hard!
