## Why?
1. Solving IEE754 by numeral usually takes 3 times of code, this plugin can resolve `+-*/` automatically.
2. Simulated human computing

## Require
babel7

## Install from npm
```bash
npm i -D babel-plugin-auto-numeral
```

## Usage
1\. add babel plugin:
```json
{
    "plugins": [
        ["babel-plugin-auto-numeral",{"precision": 2,"numeralName": "numeral"}]
    ]
}
```
2\. import numeral and use it
```js
import numeral from 'numeral'; // require numeralName first
const a = 1;
console.log(numeral(a + 0.7 * 0.7)); // 1.49
```

### options

key | type | description 
:--- | :--- | :---
precision | number/null/undefined | to pretend human calculate, this option will fix precision after every step
numeralName | string | transform the function named with the numeralName

## ⚠Warn

The expression out of numeral will be not converted, So there is a wrong example:
```js
import numeral from 'numeral';
// wrong
const square = (n) => n * n;
numeral(square(3.3)); // 10.889999999999999

// right
const square = (n) => numeral(n * n);
numeral(square(3.3));

// right
numeral(3.3 * 3.3)
```
