Atan - method of the Pm object

Returns the arctangent (invertetd tangent) of a number.

Double Atan(Double nValue)

nValue	(Double) Any valid numeric expression.

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

This method is functional also in Macro expression $.expr and in the onDraw event of the PmgCanvas object.
This method is also functional in Web panels.
