Does this example work for you?

py> (17.1).hex == (17.1).hex


py> a = 17.1
py> b = 17.1
py> a.hex == b.hex

I know why it happens -- at the REPL, the interpreter uses the same 
object for both 17.1 instances when they're part of the same statement, 
but not when they're on separate lines. I just don't know whether this 
is desirable or not.
