^* IMPORTANT NOTE: When performing decimal math, results will round to the nearest one hundred thousandth (i.e. .00001) at every step. The final answer should not include any extra zeros past the decimal point (e.g. when 4.2 is correct, 4.20 would be incorrect since it is not in simplest form.) This is intended for educational purposes only and is limited in the size and precision of numbers it can handle.

*-5.1 + 4 9.3**	.... which equals exactly 32.1
1./3.0	.... which approximately equals 0.33333 (with rounding^*)
