Overload List
| # | Signature | Description |
|---|---|---|
| 1 | function ArcCos(const X: TCplx): TCplx; | Inverse cosine of X. |
| 2 | function ArcCos(const X: TSCplx): TSCplx; | |
| 3 | function ArcCos(const X: Double): Double; | Inverse cosine. |
| 4 | function ArcCosf(const X: Single): Single; |
Overload 1: function ArcCos(const X: TCplx): TCplx;
Inverse cosine of X.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TCplx |
Returns: TCplx (complex) - Returns the inverse cosine of complex argument X.
Remarks:
To obtain an inverse cosine for X outside the interval [-1,1] use this version of the function.
Overload 2: function ArcCos(const X: TSCplx): TSCplx;
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | TSCplx |
Returns: TSCplx
Overload 3: function ArcCos(const X: Double): Double;
Inverse cosine.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | Double |
Returns: Double - Returns the inverse cosine of X. X must be between -1 and 1.
Remarks:
The return value will be on closed interval [-PI/2,PI/2], in radians for a real argument. To obtain an inverse cosine for X outside the interval [-1,1] use the complex version of the function.
