Prototype:

function ArcTan2(const y, x: extended): extended;

Description:

The ArcTan2 function calculates ArcTan(Y/X), and returns an angle in the correct quadrant. The parameters Y and X have to be between -2^64 and 2^64.

Syntax:

variable := ArcTan2(Y,X);

Part

Description

variable

A variable declared as extended

Y

Extended value of an angle in radians

X
