Formating (small numbers) in millionths help

[Brip51]

Hi,

I have a treemap and it displayes two numbers in the 'tooltip" on hover.

one is $80,400,000 displayed as 80.4M which is fine.  I recognize the capital M as "Millions"

The second numbere is .0000031

That is displayed as 3.1m (lowercase m) does that stand for  millionths ?

Also is there anyplace where the notation for numbers is listed (in help ??)

Thanks

Brian

Small m is for Thousandth, µ for millionth and n for 10 raised to -9.

I think it is used as shown here -
