5 years ago No blockchain that knows what it's doing would go anywhere near floating-point arithmetic, because different machines will produce different answers for simple calculations like A + B.
That's why they all have integer quantities for tokens/coins/assets. A Bitcoin contains 10^8 Satoshis, for example. You can only have an integer number of Satoshis.
In BigchainDB, you model an asset with N fungible pieces/parts by generating a CREATE transaction where the initial amount is N.

How does one transfer a fraction of an asset. Let say, I have 1 token, and I want to transfer 0.001 to 100 different people? So I am left with 90 tokens. How do I do that?
The docs seems to put integer constraint on amounts:
The output.amount Rule For all outputs, once output.amount has been converted from a string to an integer, it must be between 1 and 9×10^18, inclusive. The reason for the upper bound is to keep amount within what a server can comfortably represent using a 64-bit signed integer, i.e. 9×10^18 is less than 2^63.
