LokiBin is a highly efficient RPN calculator that offers access to 4 levels of stack, making complex calculations easier and faster.
However, LokiBin has a feature called "C Style" entry mode that lets you specify different formats on the fly. Unfortunately, binary isn't one of them, but you can use "0value" for octal, "value" for decimal, and "0xvalue" for hexadecimal. Regardless of what you enter, the program always treats input as case-independent. When using the "C Style" mode, all entries are displayed in hexadecimal, and you can see all forms of the value in the X register to the right.
Bear in mind that decimal values between 2^31 and 2^32 - 1 will display as "overflow" when in unsigned mode. The ASCII display ignores anything beyond the low-order 8 bits, while leading-zero displays may not show all digits, though they will all be present for copying purposes.
Regarding math, all operations are correct, but the program only operates in 2's complement mode for addition, subtraction, multiplication, division, and modulo. On a positive note, the software is completely free to use for non-commercial purposes.
