Paramete for getDecimalAmount not used

[simonbuehler]

Hi,

the getDecimalAmount method seems to be off, the $scale parameter isn't used at all, only $this->scale?

money/src/Money.php

Lines 84 to 90 in 66edcbd

	public function getDecimalAmount($scale = 2): string
	{
	return $this->instance
	->getAmount()
	->dividedBy($this->getDivider(), $this->scale, static::$roundingMode)
	->toScale($this->scale, static::$roundingMode);
	}
