Keystroke validation for a number with optional commas and decimals

I'm trying to find a keystroke validation for numbers where commas and decimals (0.000) may be entered. Any help would be appreciated.

Why not use one of the built-in options under the Format tab?

I would like for the user to be able to enter 100 or 0.100

Allow only numbers, commas and dots.
event.rc = /^[0-9,.]*$/.test(event.change);
