# TCalc
This is a minimal desktop calculator (taken from the Lex/Yacc section of
the [OCaml] manual) that can parse `3:04.5` as a time and covert it into
184.5 seconds. I'm using it for simple time calculations.
```
$ tcalc
3:04.5
184.50 (00:03:04.50)
11:52.2 / 2670 * 500
133.37 (00:02:13.37)
$
```
* Operators: + - * / ^
* Command line editing and history
* Variables (x = 21 * 2)
To help with debugging the parser, the parsed expression is emitted in
prefix syntax.
# Installation via Opam
[Opam] is the [OCaml] package manager that installs packages by
compiling them from source code.
```
$ opam install tcalc
```
# Installation from Sources
This is an [OCaml] project, it assumes you have available on a Unix
