Just add a negative lookahead and make the decimal matching possessive:

\d*[,]?\d*[.]\d++(?!%)

I would clean that up to:

\d[\d,.]*+(?!%)

I am not sure exactly what you are looking for either. You can try this, it will match both 45.00 and 45.00%

(\d*[,]?\d*\.\d+[%]?)

But the best way to test regex's is with Rubular

You can enter several lines of test data and then check that your regex matches what you expect
