The one constant is change..

Here are some constants I created that I use quite often. I made them global so they would be available to any routine I might write (just place them in a module that you can remember). You can create your own constants also or change these to your liking (you know what they say about constants..)

Global Const radian_30 = 0.52359877
Global Const radian_45 = 0.78539816
Global Const radian_60 = 1.04719755
Global Const radian_90 = 1.57079632
Global Const radian_120 = 2.0943951
Global Const radian_135 = 2.35619449
Global Const radian_150 = 2.61799387
Global Const radian_180 = 3.141592654
Global Const radian_210 = 3.665191429
Global Const PI = 3.14159265358979
