Match last 2 number in a string separated by dot

Which regex would fit better to extract the last 2 numbers separated by dot

e.g.

abc.98.76.xyz12.34 -> 12.34
qwer12.34.ty.98.76 -> 98.76

I tried \d+(?!\d+)\.\d+(?!\d+)$ but not sure if it’s the best option.

>Solution :

Possible solution is the following:

(\d+\.\d+)$

See explanation at regex101

if you need to specify exact qty of numbers:

(\d{2}\.\d{2})$

Where:
\d - any digit
+ - one o more characters
\. - dot
{2} - exactly two characters
$ - end of string
