bcal
Byte CALculator for storage conversions and calculations
bcal (Byte CALculator) is a command-line utility for storage conversions and calculations. Storage, hardware and firmware developers work with numerical calculations regularly e.g., storage unit conversions, address calculations etc. If you are one and can't calculate the hex address offset for (512 - 16) MiB immediately, or the value when the 43rd bit of a 64-bit address is set, bcal is for you.
Though it started with storage, the scope of bcal isn't limited to the storage domain. Feel free to raise PRs to simplify other domain-specific numerical calculations so it can evolve into an engineer's utility.
bcal follows Ubuntu's standard unit conversion and notation policy. Only 64-bit operating systems are supported.
