+ for addition - for subtraction * for multiplication / for division ^ for exponents <> for absolute value #pi for pi #si for sine #co for cosine #ta for tangent #as arcsine #ac for arccosine #at for arctangent Groupings ()[]{}<> cannot be inside themselves (e.g. (2(x+y)) does not work, but [2(x+y)] and 2(x)+2(y) do.) Exponents can only be multiples of .5. Notes: All trigonometry functions are in degrees, not radians. All numbers to the power of a fraction will be calculated for their positive solution, and if they are negative, will not be calculated.
v1.1: Allowed more exponents to be used. v1.2: Allowed pi and some trigonometry functions to be used. v1.3: Allow user to reset formula without pressing the green flag.
