Return value of Percentile.inc

Hi,

 

I have created a calculated column using the PERCENTILE.INC-function, but I get this error message:

Expressions that yield variant data-type cannot be used to define calculated columns.

If I wrap the VALUE-function around the expression, it works fine.

 

But why does the PERCENTILE.INC-function return a variant data-type?

regards,

Sturla

So, when the input-column is data type decimal number, the PERCENTILE-function works fine. When the input-column is data type whole number, the error "Expressions that yield variant data-type cannot be used to define calculated columns." occurs. And wrapping the VALUE-function around it fixes it. 

I don't understand why it throws this error, and why wrapping VALUE around it fixes it. From the documentation I cannot find any explanation for this behaviour. Any thoughts?
