math/bcal 2.4 DragonFly

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 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
