Takes commands in postfix notation, which means operators are entered after the operands. For example, "1 2 +" gives 3 as a result. Full Command List: Basic arithmetic (+, -, *, / ÷) ^ ** | exponentiation root | find the nth root of r ("r n root") log | find log base n of r ("n r log") trigonometric functions (sin, cos, tan, asin, acos, atan) ln | natural logarithm log10 | log base 10 floor | greatest integer <= that number (e.g. "1.2 floor" = "1") ceil ceiling | least integer >= that number (e.g. "1.2 ceil" = "2") Constants: pi ≈ 3.141593 e ≈ 2.718282 phi ≈ 1.618034
More stuff (variables, etc) planned Some stuff might glitch, but that's a fault with the system (e.g. "90 tan" = 16331239353195370 when it should be NaN)
