<div>This is also my assumption. The values used by me in the
below example<br>
are after pretty printing (i.e., convertio to strings).<br>
<br>
The actually value stored is
0.070820772089064121246337890625 (decoding<br>
it "manually", following the standard). Trying to print it
in a small C<br>
programm gives 0.00708207720890641212, which seems to be the
offical<br>
decimal represenation according to the standard. IEEE754 is
not easy ...<br>
