Line 145:

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.

:Thanks (and this won't work either in case of overflow, though this is a bit more obvious). I've just done the correction in [[Quadruple-precision floating-point format]], [[Double-precision floating-point format]] and [[Single-precision floating-point format]]. — [[User:Vincent Lefèvre|Vincent Lefèvre]] ([[User talk:Vincent Lefèvre|talk]]) 17:43, 17 August 2022 (UTC)

no longer works for me. [[Special:Contributions/64.16.131.2|64.16.131.2]] ([[User talk:64.16.131.2|talk]]) 21:45, 22 February 2023 (UTC)
