207: atan r=jordens a=matthuszagh
Adds 2-argument arctangent function. Parameters and result are `i32` integers for fast computation. Only the 16 MSBs of the inputs are used (16 LSBs are discarded). The x and y inputs can range from -1 to 1, which corresponds to `i32::MIN` and `i32::MAX`, respectively. The output ranges from -pi to pi, which corresponds to `i32::MIN` and `i32::MAX`, respectively.
