cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide.
the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972.
here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation.
you can Select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.

This code outputs various NMEA strings to a com port. The code was
originally used to test naviation programmes.
First Select the required com port and the required NMEA message string.
There is a default starting position but this can be changed to suit just by typing
in a new position.
Click on the Start button the current position displayed will change according
to the speed and heading Selected and the Selected NMEA string will be output to the com port
and will reflect the current position as displayed.
There is a text box which is normally not visible. If you change this to visible the relevant
NMEA string can be displayed.
The all mighty mouse: you can have more memory, you can have blue-ray discs but you are still using the mouse (and the keyboard) to control your computer.
The mouse pointer lets you Select objects on the screen and operate on them. What and how you operate with the mouse is pretty simple: there s an arrow on the screen that moves when you move the mouse - screen edges are the border - the area where you mouse lives. When you click it, it does something.
