# Calc - A command-line calculator

Saturday, January 12, 2019

Calc is an interactive calculator which provides for easy large numeric calculations, but which also can be easily programmed for difficult or long calculations.

I don’t do advanced math myself, but if you like command-line tools and need to do math (advanced or not) this application should be something for you.

It features both a CLI and a simple TUI. The TUI looks like this:

```
$ calc
C-style arbitrary precision calculator (version 2.12.5.4)
Calc is open software. For license details type: help copyright
[Type "exit" to exit, or "help" for help.]
; 3 * (4 + 1)
15
; 3 * 19^43 - 1
29075426613099201338473141505176993450849249622191102976
; . % (2^127-1)
47385033654019111249345128555354223304
;
```

And the CLI looks about the same:

```
$ calc '3 * (4 + 1)'
15
```

Since I’m not into math I’m not going to talk about all the features, but you can read more about them on their webpage ‘What is Calc?’.

## Installation

The package seems to be named `calc`

in most distributions, except for the Debian family where it’s named `apcalc`

.
