The method continuousModulo() does not exist on Samsara\Fermat\Types\Base\Interfaces\Numbers\NumberInterface. It seems like you code against a sub-type of Samsara\Fermat\Types\Base\Interfaces\Numbers\NumberInterface such as Samsara\Fermat\Types\Base\Interfaces\Numbers\DecimalInterface or Samsara\Fermat\Types\Decimal.
