Line 140: :Last November I added more examples to all the various floating-point formats, so that (hopefully) they all contain the same set of examples. The minimum value mentioned above was added as "smallest positive normal number". [[User:Pjacklam\|Peter J. Acklam]] ([[User talk:Pjacklam\|talk]]) 07:44, 7 August 2019 (UTC) == Conversion to binary and back == The sentence "If a decimal string with at most 33 significant digits is converted to IEEE 754 quadruple-precision representation, and then converted back to a decimal string with the same number of digits, the final result should match the original string" is only true if the quadruple precision representation is a normal number. Subnormals have less precision and proportionately fewer decimal digits are allowed. The wikipedia article for double precision floating-point format has the same issue.
