ISLEAF and IIF MDX to DAX

Question

I am currently working on migration of SSAS cube from Multidimensional to Tabular. I have many MDX queries. For example: IIF(IsLeaf([Currency].[Currency]),[Measures].[_Discount],null)

I was trying to understand, the above query with some data examples but no luck.

What is the above query mean in MDX? How could I possibly write this in DAX?

Any help is really appreciated. Thanks in advance.

Assuming your Currency hierarchy is just one level try:

IF(ISFILTERED(‘Currency’[Currency],[_Discount])
