Re: How divisible are bitcoins – the technical side

Hey,

So there is another thread asking about bc and decimal places. It is stated that the client(s) only show 2 decimal places, but there are 8 in total. Now, working on stuff, I find that it would be nice if I could transfer at least 4 decimals precision, but the full 8 would be great.

Looking at the code it seems simple enough to remove the rounding from bitcoind, but what about the receiving side? If it’s a non UI client, then it will show everything, but would I be making things overly confusing for GUI clients?

Is there any shortcoming in me patching my client to handle full precision?

I would not encourage using the extra decimal places.  They’re only intended for future use.

You are correct that above 0.01 can still have additional precision, but the recipient won’t be able to see it.  The UI will show it rounded down.
