Storage expression, unit conversion & address offset CLI calculator
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.
bcal follows Ubuntu’s standard unit conversion and notation policy. Only 64-bit operating systems are supported.
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 LBAOFFSET
- convert CHS to LBA and vice versa
- base conversion to binary, decimal and hex
- custom sector size, max heads/cylinder and max sectors/track
- minimal dependencies
