Hi Pranav,

To accomplish that you just need to use the MaskNumber and define how many decimal digits you want. The positive and negative is done by default. You can check the try now for an integer example.

This regex:

 ^[-+]?[0-9]\d*(\.\d+)?$

Allows you to match on decimals, positive and negative (it also accepts + symbols).

You can use regex in the advancedoptions or by adding data-inputmask-regex to the extended properties of the input.

I think you can just use 'decimal' as maskdefinition directly instead....
This component got a few options like allowminus, allowplus, so there's no need to use a extensive format like that.
