[](#usage)

Here is some examples about how to calculate two numbers.

### Add two numbers

[](#add-two-numbers)

```
use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->add('123456789', '123456789000000'); // 123456912456789
echo $bcMathCalculator->add('123456789', '123456789000000'); // 123456912456789
```

### Minus two numbers

[](#minus-two-numbers)

```
use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->minus('123456789', '123456789000000'); // -123456665543211
echo $bcMathCalculator->minus('123456789', '123456789000000'); // -123456665543211
```

### Multiple two numbers

[](#multiple-two-numbers)

```
use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->mul('123456789', '123456789000000'); // 15241578750190521000000
echo $bcMathCalculator->mul('123456789', '123456789000000'); // 15241578750190521000000
```

### Divide two numbers

[](#divide-two-numbers)

```
use Lee\Calculator\Calculator;
use Lee\Calculator\modules\GmpCalculator;
use Lee\Calculator\modules\BcMathCalculator;

$gmpCalculator = new Calculator(new GmpCalculator());
$bcMathCalculator = new Calculator(new BcMathCalculator());

echo $gmpCalculator->divide('123456789000000', '123456789'); // 1000000
echo $bcMathCalculator->divide('123456789000000', '123456789'); // 1000000
```

Top contributor holds 100% of commits — single point of failure

How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio. Uses a 2-year decay window.

**Popularity (30%)** — Total and monthly downloads, GitHub stars, and forks. Logarithmic scaling prevents top-heavy scores.

**Community (15%)** — Contributors, dependents, forks, watchers, and maintainers. Measures real ecosystem engagement.

**Maturity (30%)** — Project age, version count, PHP version support, and release stability.
