Regular expression for finding currency values but not dates in text

Question

I have text like the following two example strings

this book was sold for 12.00 on 12.12.2010
he paid 12.12.2010 , and puchased an amount of 15.00

Answer 1

Try this one:

(?:\s|^)\d+\.\d+(?:\s|$)

It gives two matches in my test:

12.00 
15.00
