Question 1

How to install calc.plugin.zsh with Oh My Zsh?

Accepted Answer

Clone the repository to ~/.oh-my-zsh/plugins/calc/, source calc.plugin.zsh in your .zshrc, and restart Zsh, as detailed in the installation section. This integrates it seamlessly with Oh My Zsh's plugin system.

Question 2

Can calc.plugin.zsh calculate trigonometric functions?

Accepted Answer

Yes, it supports functions like atan() for arctangent, as shown in the usage examples, but it lacks a full suite of trig functions like sin() or cos(), limiting advanced use.

Question 3

How do I convert a number to binary using calc.plugin.zsh?

Accepted Answer

Use the syntax '= "[#2] 12"' to convert decimal 12 to binary, outputting '2#1100'. The README provides clear examples for base conversions between decimal, hex, and binary.

Question 4

calc.plugin.zsh vs bc: which is better for terminal calculations?

Accepted Answer

calc.plugin.zsh is lighter and integrated into Zsh with simpler syntax, but bc offers more precision and advanced features like arbitrary-precision arithmetic. Choose based on whether you prioritize convenience or functionality.

Question 5

Is it possible to extend calc.plugin.zsh with custom functions?

Accepted Answer

No, the plugin is closed to extensions; it only includes predefined functions like sqrt() and atan(). For custom functions, users might need to modify the source code or use alternatives like the Python-based method mentioned in the README.

Question 6

What shells is calc.plugin.zsh compatible with?

Accepted Answer

It's specifically designed for Zsh and won't work in other shells like Bash or Fish. The installation instructions assume a Zsh environment, as highlighted in the plugin's name and usage.

Question 7

How to handle floating-point precision in calc.plugin.zsh?

Accepted Answer

The plugin uses Zsh's built-in arithmetic, which has standard floating-point limitations. For high precision, consider external tools like bc or Python, as the alternative implementation in the README suggests.
