--- Comment #3 from b. <newbie...@gmx.de> ---
there is an easier way to reproduce:
the value which is erroneously presented is:
'1' that's what the mantissa values should - nearly - add up to,
minus '2^-52' (for the missing terms 2^-53, 2^-54, 2^-55 ... of the mantissa,
in infinite they should add up to 2^-52),
minus '2^-51', that's the bit not set in the sample,
thus '1 - 2^-52 - 2^-51' should be the same value, and might show the same
weakness when displayed in scientific format, and, voila, it does.
easy reproducer: copy and paste '=1 - 2^-52 - 2^-51' in a cell, without the
quotes, and then set the format to 'scientific' with 14 or more decimal places.
fault: with ver. 6.2.8.2 and 7.0.0.0.a0+ : display of 10,00000000000000E+00
(my assumption - sorry @Eike - somewhere a '< vs. <=' or '> vs. >=' error ...
in the code to format the display)
i saw some other issues with bits from the mantissa having no effect on the
fraction or final value, i'll ask for that in 'ask' first.
