Number vs Int64.type

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.
