About:
Pcalc is a programmer's calculator designed for terminal use, handling binary, decimal, and hexadecimal conversions seamlessly. It supports bitwise operations, floating-point arithmetic, and features a stack-based evaluation model for complex calculations. The tool is particularly useful for developers debugging low-level code or working with memory addresses and binary data.

Key Features:

Supports multiple number bases (binary, octal, decimal, hex)
Bitwise operations and logical shifts
Stack-based evaluation for complex expressions
Interactive terminal interface with history

Use Cases:

Converting memory addresses between hex and decimal during debugging
Performing bitwise operations on hardware register values
Quick base conversions for network subnet calculations

Alternatives:

bc – bc is a general-purpose calculator, while pcalc is optimized for programmer-specific tasks like bitwise ops
calc – calc offers similar functionality but pcalc provides a more modern, stack-based interface
