Percentage of eligible salary in modeling not properly rounded

Summary:

Content (please ensure you mask any confidential information):

Hello experts,

is it possible to allow users to enter a percentage of eligible salary up to three decimals? For example our customer wants to enter 0,107 instead of 0,11.

If they enter 0.11 the available budget will be negative as in the attached screen; while if entering 0,107 should be positive.

Is there a way to define the number of decimal to be entered in modeling for percentage of eligible salary?

Kind Regards,

Valerio
