This function returns the real modulus (the remainder from division) of real number x divided by real number y, which is denoted by formula
where is the integer of round toward negative infinity.
double rmod2( double x,double y)
Returns the real modulus of real number x divided by real number y.
val1 = rmod(-4.5, 2); // val1 is -0.5 val2 = rmod2(-4.5,2); // val2 is 1.5
