Integer modulus of a division of two Real numbers
Returns the integer modulus of
x/y, i.e., mod(x, y) = x - floor(x/y)*y.
Result and arguments shall have type Real or Integer. If either of the
arguments is Real the result is Real otherwise Integer. [Note, outside of
a when clause state events are triggered when the return value changes
mod(3,1.4) = 0.2 mod(-3,1.4) = 1.2 mod(3,-1.4) = -1.2
