How to use
----------

[](#how-to-use)

### Imperative Procedural Approach

[](#imperative-procedural-approach)

```
use Math\Complex;
use Math\Complex\Operation;

$a = complex(0.3, 0.5);
$b = complex(1.0, -M_PI_2);

echo "a = " . $a->toString() . PHP_EOL;
echo "b = " . $b->toString() . PHP_EOL;
$z = Complex\sqrt($a);          //  namespace
echo "sqrt(a) = " . $z->toString() . PHP_EOL;
$z = Operation::log10($b);      //  or static call
echo "log10(a) = " . $z->toString() . PHP_EOL;

$z = Operation::add($a, $b);
echo "add(a, b) = " . $z->toString() . PHP_EOL;
$z = Complex\div($a, $b);
echo "div(a, b) = " . $z->toString() . PHP_EOL;
```

@see also [using\_example.php](./using_example.php)

### Object Oriented Approach

[](#object-oriented-approach)

```
use Math\Complex;
use Math\Complex\Operation;

$a = Complex::new(0.3, 0.5);    //  factory method contains syntactic sugar
$b = new Complex(["real" => 1, "imaginary" => -M_PI_2]); //  constructor does not

$op = new Operation($a);        //  operands' FILO inside the class
//  Operation::add($a, $b);
$c = $op->add($b)->fetch();     //  first Complex element shift from heap's top and return
print $c->asString() . PHP_EOL;

print $op->mul($c,$a)() . PHP_EOL;  //  php double magic: __call alias fetch() & __toString

print $op->atan(complex(1,2))
	->mul(complex(3,4))         //  can be chained
	->add(complex(5,6))
	->abs();
```

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.
