# Percentage Repartition

Compute a percentage repartition based on possibly fixed percentage values in a dataset

### USAGE

```js

const percentageRepartition = require('percentage-repartition');

// maxTotal must be between 0 and 100

const maxTotal = 100;

// your percentages

// if form of

// [

//   [percentage, incrementBy, canChange],

//   ...

// ]

// percentage between 0 and maxTotal (with maxTotal between 0 and 100)

// incrementBy positive integer

// canChange is a boolean value 0 or 1

// if you want a specific percentage in the repartition not to change set it to 0

let data = [

    [10, 1, 1],

    [25, 1, 0],

    [0, 1, 1],

    [4, 1, 0]

];

let result = percentageRepartition(maxTotal, data);

console.log(result);

//result: [ 100, [ 40.5, 25, 30.5, 4 ] ]

```

-------------------------------

## USE CASE SCENARIO

> Scenario : Let's say you want to split percentage between 3 people and the rest is for the "system" (owner: 40%, manager: 20%, developer: 10%, system)

Here is the config for that scenario:

```js

const maxTotal = 100;

let data = [

    [40, 1, 0], // last 0 means stay as is

    [20, 1, 0],

    [10, 1, 0],

    [0, 1, 1]

];

let result = percentageRepartition(maxTotal, data);

console.log(result);

// result: [ 100, [ 40, 20, 10, 30 ] ]

```

In this case it calculated that 30% goes back to the "system" by incrementing one by one (second digit in the fourth array ) and starting at 0 (first digit in the fourth array) until maxTotal - 40+20+10 equals 0
