Summary

Divide the value of the current complex number object by the value given by DivValue or X and Y parameters.

Pascal

 public function CDiv(const DivValue: TJclComplex): TJclComplex; overload;
public function CDiv(const X: Float; const Y: Float; const ComplexType: TComplexKind = crRectangular): TJclComplex; overload;

Parameters

Parameters	Description
const DivValue: TJclComplex	The complex number that is the denominator for the operation.
const X: Float	The real part in the rectangular representation or radius in polar coordinates of the complex number that is the denominator for the operation.
const Y: Float	The imaginary part in the rectangular representation or angle in polar coordinates of the complex number that is the denominator for the operation.
const ComplexType: TComplexKind = crRectangular	Optional. Defines whether X and Y parameters are stated in rectangular representation or in polar coordinates.

Return Value

Method CDiv returns the calling object with the changed value.

Description

Use CDiv method to perform a division operation where the current complex number object is a numerator and the value provided through either X and Y or DivValue parameters is a denominator. The complex number to be divided by could be set either as an object of TJclComplex type or a pair of its values (X;Y).

Notes

The division of the complex numbers is performed according to the following formula: (X₁;Y₁) / (X₂;Y₂) = [(X₁ *X₂+Y₁*Y₂)/(X₂²+Y₂²); (Y₁*X₂-X₁*Y₂)/ (X₂²+Y₂²)]. For leaving the value of the calling object intact use CNewDiv method to create a new resulting object of TJclComplex type.
