Converts a cartesian vector to polar coordinates.

Parameters

$vector : array{x?: float|int, y?: float|int}

Cartesian coordinates with keys 'x' and 'y'.

$degrees : bool = true

Whether the returned angle should be in degrees (default: true).

$throwable : bool = false

Whether to throw an exception if keys are missing (default: false).

throws

InvalidArgumentException

if $throwable is true and required keys are missing.

example

$polar = cartesianToPolar(['x' => 0, 'y' => 5]);
// Returns: ['angle' => 90, 'radius' => 5]

$polar = cartesianToPolar(['x' => 1, 'y' => 1], false);
// Returns angle in radians
