See @p{(link}@s{(link)}(JSON-RPC@p{link)}) for relevant advice. @p{par}

As Pieter says, bitcoin converts all user-entered values and JSON-RPC values to fixed-point 64-bit integers as soon as it gets them. All calculations except for that conversion are done using 64-bit integers. @p{par}

Bitcoin does not "use floating point", it parses numbers-containing-a-decimal-point values that come from JSON (the Number type in JSON is double-precision float; let's not restart the "we should pass numbers as strings in JSON" debate, please, there are several long threads from a couple of months ago about that) or from the GUI. @p{brk}
