Features
--------

[](#features)

- Amount is assigned randomly.
- Minimum value of each assignment is settable.
- Amount precision is settable.
- Variance factor is settable which would influence the variance of the assignment sequence.

Installation
------------

[](#installation)

Recommend to install via [composer](https://getcomposer.org/).

```
composer require "limen/redenvelope"
```

Usage
-----

[](#usage)

```
use Limen\RedEnvelope\Envelope;

$id = '123';                    // unique id
$remain = 212.23;               // envelope remain amount
$dividend = 10;                 // how many fragments to divide amount into
$minAssignment = 10.1;          // minimum value of each assignment
$precision = 2;                 // assignment precision

$varianceFactor = 1.0;          // Appropriate value should between 0.5 and 1.5, 1.0 may be the best.
                                // The greater this value, the greater the variance of the divided sequence is.

$envelope = new Envelope($id);

$envelope->setRemain($remain)
    ->setDividend($dividend);
    ->setPrecision($precision)
    ->setMinAssignment($minAssignment)
    ->setVarianceFactor($varianceFactor);

$assignment = $envelope->open();
```
