[Solved] How can I convert the polynomial data type to real?

Hi all,

I try to read a csv file which has an numberic attribute written in German format, for example: price : "100,52".  So rapidminer don't understand the comma, so it consider the attribte as "Polynomial".

Is there any operator, which convert the polynomial data type to real? For exsample: The polynomial value "100,52" to numeric value 100.52 ??? I tried the operator "Nomial to Numerical", but it does not do the job what I want.


Thanks in advance!
