WebFrom Wikipedia, the free encyclopedia. atan2 (y, x) returns the angle θ between the ray to the point (x, y) and the positive x -axis, confined to (−π, π]. Graph of over. In computing and mathematics, the function atan2 is the 2- argument arctangent. By definition, is the angle measure (in radians, with ) between the positive -axis and the ... WebSep 7, 2015 · The current atan2 methods are restricted to Float64, so we could define a native Julia version for Base.atan2(y::Number, x::Number). If we simply provide this method, ForwardDiff should work, and the Float64 version will still get called correctly. I'd just be worried about the performance of my potential native Julia implementation.
