Handling of percentage values
Form-Fields of type "decimal" can optionally be formatted as percentage. Choosing a field to be formatted as percentage assumes a field-value between 0 and 1 - which is "formatted" to a value between 0% and 100%.
If the value of this field is however computed in the form (for e.g. 25/100) the form displays 25% - as expected.
When the value is written to sharepoint the formatted value of "25" is written to sharepoint - not as you might expect 0,25.
If the column in sharepoint is as well formatted to contain percentage-values, sharepoint will show 2500% (instead of 25%).
The expected behaviour would be: the form should apply the formatting only for display, while internally maintaining the originial value - which is going to be persistet to sharepoint.

Thanks for your suggestion.
I will update the ticket if we have anything to share on this idea.
