Just tried it; seems to work fine.<br>

<p class="MsoNormal">APFloat is a wrapper class that wraps
either an IEEEFloat or a DoubleAPFloat. A union called Storage
in APFloat contains the underlying object, which is one of
those two types. The assignment APF2 = APF1</p>

What assignment? "APFloat APF2 = APF1;" calls the copy constructor,
not the assignment operator.<br>
