I'm struggling with creating proper regex pattern to match such strings:
"3" // true
"3." // true
"3.1" // true
"3.22" // true
And such strings should fail matching:
"3.." // false
"3.222" // false
My current regex /^\d+(\.\d{1,2})*$/
matches only decimal numbers. I've tried several updates to it but cannot accept all rules.

Make the decimal part optional + you forgot to put \
before first d
, and remove *
from the decimal part.
/^\d+(\.\d{0,2})?$/
