When I execute the following:

[5,10,15,20].map(v => format('$.1s')(v * 1E9))

it returns:

["$5G", "$10G", "$20G", "$20G"]

However, to me it would make more sense if the combination of SI and currency would not result in G for giga, but B for billion, preferably localized.

Is support for this planned? Thanks.
