Summary
Subtracts the value given by MulValue or X and Y parameters from the value of the current complex number object and creates a new resulting object of TJclComplex type.
Pascal
public function CNewSub(const SubValue: TJclComplex): TJclComplex; overload;
public function CNewSub(const X: Float; const Y: Float; const ComplexType: TComplexKind = crRectangular): TJclComplex; overload;
Parameters
| Parameters | Description |
| const SubValue: TJclComplex | The complex number that is the subtrahend. |
| const X: Float | The real part in the rectangular representation or radius in polar coordinates of the complex number that is the subtrahend. |
| const Y: Float | The imaginary part in the rectangular representation or angle in polar coordinates of the complex number that is the subtrahend. |
| const ComplexType: TComplexKind = crRectangular | Optional. Defines whether X and Y parameters are stated in rectangular representation or in polar coordinates. |
Return Value
Method CNewSub returns a newly created object of TJclComplex type that contains the value of the subtraction.
Description
Use CNewSub method to perform a subtraction operation where the current complex number object is the minuend and the value provided through either X and Y or DivValue parameters is the subtrahend and to create a resulting object of TJclComplex type. The complex number to be subtracted could be set either as an object of TJclComplex type or a pair of its values (X;Y).

Notes
The subtraction of the complex numbers is performed according to the following formula: (X1;Y1) - (X2;Y2) = (X1-X2;Y1-Y2). For changing the value of the calling object instead of creating a resulting object of TJclComplex type use CSub method.
