# bigdash
Re-implement lodash math functions with [big.js](https://github.com/MikeMcl/big.js).
## Why?
Lodash:
```js
sum([0.1, 0.2]); // 0.30000000000000004
```
Bigdash:
```js
sum([0.1, 0.2]); // 0.3
```

## Install
```bash
npm install --save bigdash
```
## Usage
### add()
```js
import { add } from 'bigdash';
add(0.1, 0.2); // 0.3
```
### divide()
```js
import { divide } from 'bigdash';
divide(0.1, 0.2); // 0.5
```
### mean()
```js
import { mean } from 'bigdash';
mean([0.1, 0.2]); // 0.15
```
### meanBy()
```js
import { meanBy } from 'bigdash';
meanBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], 'foo.bar'); // 0.15
meanBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], ['foo', 'bar']); // 0.15
meanBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], (item) => item.foo.bar); // 0.15
```
### multiply()
```js
import { multiply } from 'bigdash';
multiply(0.1, 0.2); // 0.02
```
### subtract()
```js
import { subtract } from 'bigdash';
subtract(0.3, 0.2); // 0.1
```
### sum()
```js
import { sum } from 'bigdash';
sum([0.1, 0.2]); // 0.3
```
### sumBy()
```js
import { sumBy } from 'bigdash';
sumBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], 'foo.bar'); // 0.3
sumBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], ['foo', 'bar']); // 0.3
sumBy([{ foo: { bar: 0.1 } }, { foo: { bar: 0.2 } }], (item) => item.foo.bar); // 0.3
```
