Syntax

FLOAT atan2 ( <FLOAT y> , <FLOAT x>)

Description

Returns the arctangent of a certain value. It is computed as the arc tangent of y/x. The signs of the arguments are used to perform the calculation.

This function performs an arctangent calculation on a certain value and returns an angle between but not including -180000 and 180000 (-180-180º).

Parameters

FLOAT y - The Y value to be performed an arctangent calculation on.
FLOAT x - The X value to be performed an arctangent calculation on.

Returns

FLOAT : The arctangent result of the specified value, an angle between but not including -180000 and 180000 (-180-180º).

Notes

The angle value returned by this function is in thousandths of degrees, as most angles within Bennu are.
