How do we change the data type from nominal to numerical in rapidminer?

I don't want unique integers substituting my values or use dummy coding (Basically what Nominal to Numerical Operator does)

I even tried using Real to Integer operator. But that did not change the datatype from Nominal to Numerical Inplace.

Is there any operator to just convert the values inplace?

Motive: Need to feed my data to Linear Regression. And Linear Regression Operator demands Numerical values

    Hi,
    if you don't want unique integers nor dummy coding, what do you want? Target encoding?

    Its type says Nominal. (Can refer the screenshot)
    I want to convert it to numerical type

    As simple as

    5.00 --> 5

    Hi,
    Ahh, i think you want to use the Parse Numbers operator.

    Cheers,
