> `Int` and `UInt` are aliases for the system’s native integer types such as `Int64` and `UInt64`, but there’s no such thing for `Float` to refer to the system’s native float type such as `Float64`—why not?

This exact question seems to come up so often that maybe it should be in the FAQ:

- 2/2014: [If (in my system) Int is an alias for Int32, then why there is no Float alias for Float32/64?](https://groups.google.com/d/msg/julia-users/1tDvMbfCUEE/BJCu0-S7OawJ)
- 4/2013: [typealias for Float](https://groups.google.com/d/msg/julia-users/WXTmzMaj4pc/xsigqax_qi0J)
