godc

A dc implementation written in golang

---

dc is a very old reverse-polish notation calculator, written even before the C language was made.

In reverse-polish notation, instead of writing 2 + 2, you write 2 2 +. The operator comes later, while awkward at first glance, it can help avoid confusion at times

All commands must be space seperated, the only exception is conditional commands, like =m

---

Features

• Decimal numbers supported
• Basic Arithmetic + modulo, square root, modular exponentiation
• A Stack to store numbers
• Registers, strings, and macros for extra command
• Conditional operators
• Loops can be implemented using registers, macros and conditionals
• For a full list of supported commands, do ? inside godc

Limitations

• Unlike dc where the register can store multiple values, in godc a register can only store one value at a time
• In nested macros, you cannot just come out of 1 macro, you exit out of all of them (Q)
• Precision control not implemented
• Script (-e) and file mode (-f) not implemented, only interactive mode supported for now
• certain dc commands like P, S, L, a, Z, X, :, ; not implemented
