And one zillion equals ten zillions...

If you use the Rogers system rather than the Magnusson system then it is not equal, I think.

And also one hundred zillions, and even one zillion zillions.

Yeah ok, we got thay from the parent comment.

Yeah although we would probably have said "two eight zillion" not "twenty eight zillion", and in the kind of conversations we'd have, it wouldn't really matter.

"Where is the stack base supposed to be?"

"O X 8 zillion"

"Oh, the system crashed with stack pointer at 0 X two eight zillion, something must have gone badly wrong!"

Funny how the same informal-isms crop up in disparate teams -- I've heard/used the same thing.

You could have enforced reduction rules so that the only valid zillion value is [0-F].[0-F]...
