> I'd start with a 20 character buffer (because int64 will never need more) Just in case anyone is wondering, this is because the maximum number of decimal digits for a given number of bits is given by: digits(bits) = ceil(bits * log10(2)) This can be generalized to any number of bits. digits(32) = 10 digits(64) = 20 digits(128) = 39 digits(256) = 78 digits(512) = 155 digits(1024) = 309
