what if RAI value is raised exponentially? we can't send 0.0001 Rai?
Decimal points in finance is never a good idea.
We use a 128 bit integer to represent account balances, this is too large to present to the user so we defined a set of SI prefixes to make the numbers more accessible and avoid confusion. The reference wallet uses Mrai as a divider.
Grai = 1000000000000000000000000000000000, 10^33
Mrai = 1000000000000000000000000000000, 10^30
krai = 1000000000000000000000000000, 10^27
rai = 1000000000000000000000000, 10^24
mrai = 1000000000000000000000, 10^21
urai = 1000000000000000000, 10^18
