Convert negative values to positive values

Hi everybody!

I have a column with positive and negative numbers but I need all numbers without the minus. Is there any way to eliminate the minus? I thought about something like absolute value bars, but I havent found a way yet.

Please let me know if somebody has an idea how to make this work with KNIME.

Thanks and kind regards!

Hi @Parn

In the Math Formula node there is an option abs(x).

Oh, I probably missed that. Thank you!


Is there a way to transform multiple columns?

HI @Stervis
yes there is. Take a look at the Math Formula Multi Column
