The Big Number library comes in two distinct parts: an expression template
|
|
enabled front end <code class="computeroutput"><span class="identifier">big_number</span></code>
|
|
that handles all the operator overloading, expression evaluation optimization,
|
|
and code reduction, and a selection of backends that implement the actual arithmetic
|
|
operations, and need conform only to the reduced interface requirements of
|
|
the front end.
