Nominal to numerical wrong convertation

Question

Hello all,

i have some problems with the Nominal to Numerical Operator:

i use the follow data set:

0 1 2 3 4 5 6 7 8 9 10 
30 31 32 
33 34 35 
36 37 38 39 40 41 42 43 44 45 46

as Dat-Data  ( retail.dat)

My Workflow is:

Read Csv -> Split -> Replace Missing -> Nominal to Numerical

I have set the separation-char to  , (comma) to try the separation with the split-operator. the split operator does his job
and return alle attributes as nominal. now i wanted to convert nominal to numerical and instead of numbers like 30 32 ...
i get the numbers 0 , 1 , 2 ....

Is this a bug or did i something wrong . ???

greetings

Hi,
as haddock indicates: The operator documentation tells everything. Try to read the documentation of the "parse numbers" operator and you will be enlightened.
