Exponent calculation

[indhu]

Hi all, 

I have a column decimal with varying powers say 0,10,18,28 etc. Another column amount, which contains different values. My task is to create a new column which does the following function,

New column = if decimal <> 0 then (0.05*amount)/10^decimal 
else (0.05*amount)/10

I can't figure out how to do this. Creating a measure with exp option provides a feature to use an exponential function with a specific number only. I would like to generate exponential value for a column and perform the above operation. 

Can somebody help me in pointing out in the right direction?

Thanks,

Indhu.

anyone worked with exponent calculation using calculated columns orr measures?

Hi @indhu,

I entered a table as you descried and create a new column as below to meet your requirement.

Column = IF(Table1[decimal]<>0 , (0.05*Table1[amount])/10^Table1[decimal],0.05*Table1[amount]/10)

For more details, please check the pbix as attached.

Hi @v-frfei-msft,

Thanks frank.

This is a calculated column, right? Is there any way to generate the same result in a custom column?

Thanks,

Kanthi.

Hi @indhu,

In power query, we can add a custom column using the formula as below.

Custom = if [decimal]<>0 then 0.05*[amount]/Number.Power(10,[decimal]) else 0.05*[amount]/10

Here is the result as we excepted.

For more details, please check the pbix as attached.
