-- math.fmod() is incoherent: it uses using an Eudidian integer division towards 0 (truncating instead of using floor),
-- so with negative values of x (with a positive divisor y) it returns a negative remainder.
-- Using the operator (x % y) is not equivalent (it could be correct but in some versions of Lua, it has incorrect
-- roundings when operands are integers, due to incorrect internal "optimization" using integer arithmetic
-- but changing the rounding direction).
-- This version always returns a remainder with the same sign as y (not the same sign of x), using math.floor().
-- When y is positive (in this module it is always the case with y a constant), the return value always
-- will also be positive, in [0, y). When y is negative, the result will also be negative in (y, 0].
-- The return value will be NaN if any operand is infinite or NaN or if y is zero.
