Regex Go mismatch

Question

I have developed some regex in regexr where it works as expected, but when I use it in Go it seems to be mismatching strings.

(\+|-)?(((\d{1,3}[, ])(\d{3}[ ,])*\d{3})|\d+)( ?[\.,] ?(\d{3}[, ])*\d+)?

For example in regexr the following input does not match:

1.12,4.64

But in Go it does match.

Are you aware, that there are many flavours of regular expressions, and something that works for one engine might not work for another? — Ainar-G, Feb 11 '15 at 12:58

^(\+|-)?(((\d{1,3}[, ])(\d{3}[ ,])*\d{3})|\d+)( ?[\.,] ?(\d{3}[, ])*\d+)?$

Try with anchors.^$ will disable partial matching.See demo.
