lol but the point remains that there are decimals if there were no decimals a satoshi would the unit we use to calculate the total supply.
Discussion
The base unit is how we calculate the total supply.
CAmount GetBlockSubsidy(int nHeight, const Consensus::Params& consensusParams)
{
int halvings = nHeight / consensusParams.nSubsidyHalvingInterval;
if (halvings >= 64)
return 0;
return 50 * COIN >> halvings;
}
The total supply is a function of the halving calculation.
2.1 quadrillion is a bit of a mouthfull compared to 21 million
