bc-gh is a feature-rich implementation of the standard Unix dc(1) calculator and the POSIX bc(1) language. It provides a powerful, scriptable command-line environment for arbitrary-precision arithmetic. This version includes significant GNU and BSD extensions, making it a robust and versatile tool for developers and scientists.
Key Features:
  • Arbitrary precision arithmetic
  • Full POSIX bc and dc compatibility
  • Interactive shell with readline support
  • Extensive math library (standard, scientific, and more)
Use Cases:
  • Scientific and engineering calculations requiring high precision
  • Financial computations where floating-point errors are unacceptable
  • Scripting complex mathematical operations in shell scripts
Alternatives:
  • GNU bc – bc-gh is a modern, actively maintained alternative with more features and better standards compliance.
  • dc – The traditional RPN calculator; bc-gh includes a compatible dc interpreter with extensions.
