Summary: Ten functions (degrees or radians) with extensive help and
argument checking. Instructions: Includes the following complex math functions:
rectangular-to-polar, polar-to-rectangular, clear complex, conjugate, inverse, addition, subtraction, multiplication, division, and swap complex numbers. For functions that require a single complex argument, X+iY, X should be in stack position 1 and Y in position 2. For functions that require two complex arguments, X2+iY2 and X1+iY1, X1 should be in stack position 1, Y1 in position 2, X2 in position 3, and Y2 in position 4. P->R function assumes the magnitude is in stack position 1 and the angle in position 2. The results are returned using the same convention. Multiplication and division are preformed by first converting the number to polar form. Why another complex number scrip: Perry's doesn't work in radians, doesn't provide help, jumbles the stack if the right number of arguments are not entered, and it's not efficient. Katsumata's rectangle-to-polar function gives the wrong angle [atan(Re/Im)], and it bombs out when the imaginary part is zero. Hey, this stuff is not easy, and these are the guys that inspired me. We all owe them thanks. Code:
