# luaqalculator
This library implmenets some glue between libqalculate and lua, which is used for my bot's calculate function.
2022-04-10 10:44:13 +00:00
Calling this library a "binding" would probably be a mistake seeing that it simply isn't a binding, but rather a thin library that allows calling the "CalculateAndPrint" function from lua.

That being said, it's more than enough for my particular use case.
# Building
2022-05-20 18:17:07 +00:00
To make everything to compile with as few steps as possible you will need `make`, `g++`, `libqalculate` and `lua5.1` (which is the default target).

Once you have all of the above, simply type `make` and it will produce the needed `libqalcaulator.so` library.
If you wish to compile against a different version, simply change the variable `LUA_VERSION` in the makefile to the one you need.
# Usage
```lua
qalc = require("libqalculator")
print(qalc.qalc("sin(3 rad)")) -- Approximate mode (will return an interval with approximate values)
print(qalc.qalc("sin(3 rad)", true)) -- Exact mode (will return "sin(3 rad)" to avoid approximation)
```
