The atan2 function computes the four-quadrant arctangent of fixed-point inputs using an 8-bit lookup table as follows: Divide the input absolute values to get an unsigned, fractional, fixed-point, 16-bit ratio between 0 and 1. The absolute values of y and x determine which value is the divisor.

WebAug 7, 2024 · It can get around the previous issue by taking both x and y in as separate arguments. Whereas the syntax for arctan is arctan ( y / x), the syntax for arctan2 is arctan 2 ( y, x). Knowing the signs of x and y separately can determine if the angle lies in any of the four quadrants. The range of arctan2 is - π ≤ arctan 2 ( y, x) ≤ π or in ...
