Computed twig element does not work with php 8.0

I'm not sure if this is the same issue, I'm using PHP 8.1. The following always results in a Division by Zero error:

numerator:
  '#type': number
  '#title': Numerator
  '#states':
    visible:
      ':input[name="metric_type"]':
        value: Percentage
denominator:
  '#type': number
  '#title': Denominator
  '#states':
    visible:
      ':input[name="metric_type"]':
        value: Percentage
  '#min': 1
calculated_percentage:
  '#type': computed_twig
  '#title': 'Calculated %'
  '#title_display': none
  '#description_display': invisible
  '#template': '{{( data.numerator / data.denominator )}}'

This is also the case using the number_format filter.
