Programmer's RPN calculator with bitwise operations.
Has all main bitwise operations (like and, or, not etc.), supports binary, octal, hexadecimal and decimal numbers representation (works with floating point numbers), raw number and exponential views to give insight on inner machine representation of a number, complex numbers support etc.
Some key combinations:
1. It doesn't stop you from entering numbers in selected numeral system only (the one selected in main menu affect numbers display in stack and evaluation results representation only). To enter number in other numeral system but decimal, use "Mod+#" combinations, where # can be 2 for binary, 8 for octal or 16 for hexadecimal numbers, use "Mod+0" to go back to decimal input.
2. "C" is "Clear" input, "Fn+C" ("CA") is "Clear All" (both input and stack). "<<" and ">>" is bit shifts, "xBn" is to enter "e" for exponential numbers input, "Mod+xBn" ("+bj") is to enter "j" as postfix to designate imaginary part of complex number.
"Mod" also turns main arithmetic operation keys into statistics operators "σ" (standard deviation), "μ" (mean), "Π" (product), "gμ" (geometric mean) and "Σ" (summa). These operations work on whole stack, so to calculate sum of a set of numbers just push them onto empty stack one by one, push "Mod++" operation and hit "Execute" ("=" button).
3. Almost all onscreen keys have keyboard bindings.
All top row is for numbers input, Ctrl switches on Fn, backspace is a backspace and equal sign/comma/semicolon is for "=" button (a.k.a. "Execute").
Hexadecimal numbers "A"-"F" are uppercase keyboard buttons (i.e. press "Shift+A" to enter "A", "Shift+B" to enter "B" etc). Underscore (_) switches number sign to +/-, and dot (.) is for decimal point.
Star (* or letter "a"), plus (+ or letter "s"), minus (- or letter "f") and slash (/ or letter "v") are for multiplication, addition, substruction and division. Hash (# or "d"), ampersand (& or "k"), exclamation (! or "l"), letter "z" and dollar sign ($ or "x") are for XOR, AND, NOT, OR and AND NOT bitwise operations.
Parenthesis (letters "h" and "j") are for push and pop. Enter is for "=" ("Execute"). Backslash (letter "b") is for power, space is for push. "m" letter switches "Mod" button. "c" letter is for "Clear".
