I'll be dumping some result tables here

op	3	-3
5	op(5,3)	op(5,-3)
-5	op(-5,3)	op(-5,-3)

matlab

matlab.mod
2|-1
1|-2
matlab.rem
2|2
-2|-2

Python

numpy.fmod
2.0|2.0|
-2.0|-2.0
numpy.mod / numpy.remainder /  %
2.0|-1.0|
1.0|-2.0
math.remainder
-1.0|-1.0|
1.0|1.0

C

c99 fmod
2|2|
-2|-2|
c99 remainder
-1|-1|
1|1|
