Thanks for sharing!

FYI. SHARP pocket computers use 10 digits BCD to display values and store values in variables and 12 digits internally to evaluate expressions. For example (SQR is sqrt): SQR 2 * SQR 2 2 X=SQR 2 X*X 1.999999999 There is a small penalty to use variables to store (temporary) results. It is sometimes beneficial to "inline" expressions to preserve or increase accuracy.
