Rmod2

Description

This function returns the real modulus (the remainder from division) of real number x divided by real number y, which is denoted by formula

$x-N*y$

where $N$ is the integer of $\frac{x}{y}$ round toward negative infinity.

Syntax

double rmod2( double x,double y)

Parameter

x:

is the dividend. Can be any real number.

y

is the divisor. Can be any real number.

Return

Returns the real modulus of real number x divided by real number y.

Examples

val1 = rmod(-4.5, 2);    // val1 is -0.5
val2 = rmod2(-4.5,2);   // val2 is 1.5
