- Support bignumber, use [decimal.js](https://github.com/MikeMcl/decimal.js)
- Support [Mathematics functions](http://mikemcl.github.io/decimal.js/#methods)
## Usage
1. Install by coc.nvim command:
```
:CocInstall coc-calc
```
2. Input calculate expression in any buffer
```
sin(PI / 2) =
```
## Commands
- `calc.appendWithCursor` Calculate and append in front of cursor
- `calc.append` Calculate and append
- `calc.replaceWithCursor` Calculate and replace in front of cursor
- `calc.replace` Calculate and replace

```vim
" append result on current expression
nmap ca (coc-calc-result-append)
" replace result on current expression
nmap cr (coc-calc-result-replace)
```
## Configurations

- `calc.highlight`, enable calc highlight, default: `true`
## Vim API
### calc.calculate
```vim
let result = CocAction('runCommand', 'calc.calculate', '1.5 * PI')
```
## Operators
Precedence is from highest to lowest.
