Atan - method of object Pm

Returns the arctangent (invertetd tangent) of a number.

Atan(nValue As Double) As Double

n = Pm.Atan(nValue)

nValue	(Double) Any valid numeric expression.

Real number in the range from -Pi/2 to +Pi/2.

The method can also be called in the graphic item events for Web panels.

The method is functional also in Macro expression $.expr and in the onDraw event of the PmiCanvas graphic item.

Arccos = Pm.Atan(-x / Pm.Sqrt(-x * x + 1)) + 2 * Pm.Atan(1);
Arcsec = Pm.Atan(x / Pm.Sqrt(x * x - 1)) + Pm.Sign(x - 1) * 2 * Pm.Atan(1);
Arccosec = Pm.Atan(x / Pm.Sqrt(x * x - 1)) + (Pm.Sign(x) - 1) * 2 * Pm.Atan(1);
