Overload List
| # | Signature | Description |
|---|---|---|
| 1 | function CAbs1(const Z: TCplx): Double; | Returns the approximation of the norm of Z. |
| 2 | function CAbs1(const Z: TSCplx): Single; |
Overload 1: function CAbs1(const Z: TCplx): Double;
Returns the approximation of the norm of Z.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Z | TCplx |
Returns: Double - the approximation of the norm of complex number: |Z| = abs(Z.Re) + abs(Z.Im).
Remarks:
The following relations are true: (CAbs(Z1) < CAbs(Z2)) < = > (CAbs1(Z1) < CAbs1(Z2)) and (CAbs(Z1) > CAbs(Z2)) < = > (CAbs1(Z1) > CAbs1(Z2)). This function can be used to speed up comparing operations between complex numbers.
Overload 2: function CAbs1(const Z: TSCplx): Single;
| # | Name | Type | Description |
|---|---|---|---|
| 1 | Z | TSCplx |
Returns: Single
