Summary: Math functions for complex numbers (including conjugate and inverse).
Instructions: Includes math functions for complex numbers (x+jy). Assumes x is in stack position 1 and y is in stack position 2. For two complex numbers, x1 in position 3, y1 in position 4, x2 in position 1 and y2 in position 2.
Includes inverse of complex number (inv z = 1/z), conjugate ( conj (x+jy) = (x-jy)) swap for swapping x2 y2 with x1 y1. Also includes polar and rectangular conversion. Assumes angle is in position 2 and magnitude in position 1. The polar/rectangular conversion correctly handles cases where angles are 0, 90, 180, 270, and 360. Polar conversion gives all positive angles (300 instead of -60 for example). CLRx clears both position 1 and 2 (x and y). All functions, with the exception of polar/rectangular conversion, assume number is in rectangular form. Code:
