Function std.math.remainder

Calculate the remainder x REM y, following IEC 60559.

REM is the value of x - y * n, where n is the integer nearest the exact value of x / y. If |n - x / y| == 0.5, n is even. If the result is zero, it has the same sign as x. Otherwise, the sign of the result is the sign of x / y. Precision mode has no effect on the remainder functions.

remquo returns n in the parameter n.
