Thank you for the forge, but it still has a bug.
the number input widget still allow type letter "e" into the input. Please fix it :)

Values placed inside an input that have a mask applied aren't received correctly by a local variable, making it unusable for data intake. Also, for some reason, allows for letters to be placed on an input that has the "Number" data type.

This mask solve my problems with other masks, paste with decimal amounts and show correctly a pre-filled value.
