Calculates the tangent of a number.
Tan ( expression )
| expression | Value in radians. |
1° = pi / 180 radians.
Note that Tan() is "infinite" for ... -3PI/2, -PI/2, PI/2, 3PI/2, 5PI/2, ... and tends to return 1.63317787283838e+016 for such multiples of Pi-halves.

Example()
Func Example()
; Assign a Local constant variable the approximate PI number.
Local Const $PI = 3.141592653589793
; Assign a Local variable the tangent of PI / 4.
Local $fTan1 = Tan($PI / 4)
; Display the result.
MsgBox($MB_SYSTEMMODAL, "", $fTan1)
; Assign a Local variable the formula to switch from radian to degree (equals to one degree in radian).
Local $iDegToRad = $PI / 180
; Assign a Local variable the tangent of 90 degrees (firstly converted to radians).
Local $fTan2 = Tan(90 * $iDegToRad)
; Display the result.
MsgBox($MB_SYSTEMMODAL, "", $fTan2)
