Immediate means it's stored in the OOP itself, like SmallInteger in 32 bits.

Variable word is like variable byte (ByteArray) I suppose, variable size, with indices instead of named instance variables, but each index points to a full word (I guess either 32 or 64bit depending on the VM)

Hi!

I have stumbled on:

Float immediateSubclass: #SmallFloat64
�� instanceVariableNames: ''
�� classVariableNames: ''
�� package: 'Kernel-Numbers��

Float variableWordSubclass: #BoxedFloat64
�� instanceVariableNames: ''
�� classVariableNames: ''
�� package: 'Kernel-Numbers��

What are immediate subclass and word variable?

Cheers,
Alexandre
