double Sqrt(const double X);
Square root.
| # | Name | Type | Description |
|---|---|---|---|
| 1 | X | const double |
Returns: Returns double precision square root of the given number X.
Remarks:
Math387.Sqrt uses SSE2 SQRTSD on Win32/Win64 (single hardware instruction) via the SVML override path; non-Windows targets fall back to System.Sqrt through the PURE_PASCAL include. Faster than the x87-FPU FSQRT that Delphi's built-in System.Sqrt historically used.
