Power Query Conditional Column with NULL Values

Hi,

I need to clean up sensor data. I know that if the sensor data is a negative number or below a certain treshhold, it should be zero.

I do this with a conditional column, if below the treshhold I set them to zero. But there are also null values. So I do an if elsestatement for null = null. 

But I can error for the rows which contain null. I have to replace errors and make them null again. Is there an another approch to this so I don't get errors?

If you start comparing anything with null you get errors.

@numersoz what is the data type of this column? Is it a number? Change it to the number and then apply the conditional logic.

Hi,

 

Thank you this did solve the problem. I am not sure why the otherway didn't work.

@numersoz ,

 

That's because if you compare null with any value, you are gonna get error. 

So start checking the null values.
