Hi thanks for reading,
My question is, if I for example have the followig expression in power query:
Table.TransformColumnTypes(#"Filtered columns",{{"Income", Int64.Type},....Is it better than this?
Table.TransformColumnTypes(#"Filtered columns",{{"Income", type number},....Or whats the difference between the two?
Because Int64 is the data type power bi automatically detected and I'm confused
Thanks again,
Best regards,
E.

Hello @Anonymous
to complete @mahoneypat answer, type number are all number (1, 1.2 etc.) whereever Int64 stands for integer meaning whole number (3,5,7)

If you have decimal numbers, you will need number. I did a quick test on a column with many rows and the file size didn't change when i used the two types.
