bcal (Byte CALculator) is a REPL CLI utility for storage expressions, unit conversions or address calculations. If you can't calculate the hex address offset for (512 - 16) MiB, or the value when the 43rd bit of a 64-bit address is set mentally, bcal is for you. It has a bc mode for general-purpose numerical calculations. Features: * evaluate arithmetic expressions involving storage units * perform general purpose calculations (using bc) * convert to IEC/SI standard data storage units * interactive mode with the last valid result stored for reuse * show the address in bytes * show address as LBA:OFFSET * convert CHS to LBA and vice versa * base conversion to binary, decimal and hex * custom sector size, max heads/cylinder and max sectors/track
