In the dataset, we have an attribute size that contains the size of the app like 12M, 45K, etc. I would like to calculate the 12M as 12*1000000 and replace the value as 12000000 and for 45K as 45*1000 and replace the value as 45000.
I have added a map operator and given the regular expression. But it not calculating in the Rapid miner. Please help
