Function idsp::atan2

pub fn atan2(y: i32, x: i32) -> i32

2-argument arctangent function.

This implementation uses all integer arithmetic for fast computation.

Arguments

• y - Y-axis component.
• x - X-axis component.

Returns

The angle between the x-axis and the ray to the point (x,y). The result range is from i32::MIN to i32::MAX, where i32::MIN represents -pi and, equivalently, +pi. i32::MAX represents one count less than +pi.
