guinness Posted October 4, 2014 Posted October 4, 2014 There was an undocumented function for years in the UDFs, but as no requests were made for it be added, a decision was made to remove it.

czardas Posted October 4, 2014 Posted October 4, 2014 (edited) I have never used it myself but it seems quite useful. I have seen it used in a few scripts. Edited October 4, 2014 by czardas operator64 ArrayWorkshop
eukalyptus Posted October 4, 2014 Posted October 4, 2014 You can use this: Func _ATan2($fY, $fX) Local $aResult = DllCall("msvcrt.dll", "double:cdecl", "atan2", "double", $fY, "double", $fX) If @error Then Return SetError(@error, @extended, False) Return $aResult[0] EndFunc ;==>_Atan2 Shane0000 1 DirectSound UDF Direct2D UDF
AndyG Posted October 4, 2014 Posted October 4, 2014 Func atan2($y, $x) Return (2 * ATan($y / ($x + Sqrt($x * $x + $y * $y)))) EndFunc ;==>atan2 Shane0000 1
Shane0000 Posted October 4, 2014 Author Posted October 4, 2014 Thanks guys, The DLL call ended up taking 3x longer to return $A = TimerInit() $_ATan2_A = _Atan2_A(3,4) ConsoleWrite('_ATan2_A ' & $_ATan2_A & ' ms:' & TimerDiff($A) & @CRLF) $B = TimerInit() $_ATan2_B = _Atan2_B(3,4) ConsoleWrite('_ATan2_B ' & $_ATan2_B & ' ms:' & TimerDiff($B) & @CRLF) Func _ATan2_A($fY, $fX) Local $aResult = DllCall("msvcrt.dll", "double:cdecl", "atan2", "double", $fY, "double", $fX) If @error Then Return SetError(@error, @extended, False) Return $aResult[0] EndFunc ;==>_Atan2 Func _atan2_B($y, $x) Return (2 * ATan($y / ($x + Sqrt($x * $x + $y * $y)))) EndFunc _ATan2_A 0.643501108793284 ms:0.0634787897217576 _ATan2_B 0.643501108793284 ms:0.0193857381785008 Both of the examples are much simpler than the previous user functions I had found.
Shane0000 Posted October 4, 2014 Author Posted October 4, 2014 BTW , I will be using this for gps related calculations, distance, bearing etc I was going to use it in to get angle based on a point on a circle at one time too for a pathing project I was working on just a couple of examples of a use for ATan2
