Show HN: bcal – Storage & general-purpose CLI calculator for programmers

• apjana 7y ago
  `bcal` (Byte CALculator) is a REPL CLI utility for storage expression evaluation, unit conversion and address calculation. 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. Alternatively, it can also invoke `calc` which works better with expressions involving multiple bases. The latest version 2.2 is released today. ### Features - REPL and single execution modes - evaluate arithmetic expressions involving storage units - perform general purpose calculations (using bc or calc) - works with piped input or file redirections - 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 - minimal dependencies
