Other - Digits and decimal points

Hello everyone, I'm having an issue with decimal points and my Regex.

Lets say I have something like:
[21,[10355.0,8039.48,0.00895691]]

I use the regex

which works just fine, however when I have something like:
[21,[10355,8039.48,0.00895691]]
that does not have a decimal point in one of the digit groups I don't get any matches.

Can someone please help me with my number capture groups to also allow for a group without a decimal point..
Thanks

So don't require the decimal point. If you're confident that the numbers themselves are valid,

If not then make the fractional part optional.
