Currency Formats

[mjkeaton]

As described in a comment to #71, there is ambiguity around currency formatting of bitcoin values, especially regarding trailing zeros (e.g., some copies display 100.00000000 BTC other times 12.33882 BTC..)

Taken from Bitcoin Design Guide.

Furthermore, it should be decided whether to follow the "Satcomma standard", e.g. 0.00 025 000 bitcoin.

Questions:

• Should all trailing zeros of bitcoin values be displayed?
• Should we adhere to the "Satcomma standard"?

What do you think? @cryptosalomao @mtbitcr

@HubertusVIE we need also your opinion.

Q: Should all trailing zeros of bitcoin values be displayed? A: It is customary in banking to display a fixed number of decimals.

Q: Should we adhere to the "Satcomma standard"? A: I agree that is is much better readable.

Also note: All Banking Systems I know allow per-currency decimal settings for display standards. I remember mostly 0, 2 or 3 decimals. For Bitcoin, Phoenix has the a pretty good usability. From theirs, and improved, I suggest in the user settings a choice for several Bitcoin units:

• sat 0.00 000 001 bitcoin (Format 0 no decimals)
• bit 0.00 000 1 bitcoin (Format 0.00 with 2 decimals
• mil (irrelevant IMHO)
• btc (Format 0.00 000 000 with 8 decimals)

Obviously locale for other conventions, such as ./,/ and number grouping.
