<p>
|
||||
The <code class="computeroutput"><span class="identifier">debug_adaptor</span></code> type
|
||||
is used in conjunction with <code class="computeroutput"><span class="identifier">number</span></code>
|
||||
and some other backend type: it acts as a thin wrapper around some other
|
||||
backend to class <code class="computeroutput"><span class="identifier">number</span></code>
|
||||
and intercepts all operations on that object storing the result as a string
|
||||
within itself.
|
||||
</p>
|
||||
<p>
|
||||
This type provides <code class="computeroutput"><span class="identifier">numeric_limits</span></code>
|
||||
support whenever the template argument Backend does so.
|
||||
</p>
|
||||
<p>
|
||||
This type is particularly useful when your debugger provides a good view
|
||||
of <code class="computeroutput"><span class="identifier">std</span><span class="special">::</span><span class="identifier">string</span></code>: when this is the case multiprecision
|
||||
values can easily be inspected in the debugger by looking at the <code class="computeroutput"><span class="identifier">debug_value</span></code> member of <code class="computeroutput"><span class="identifier">debug_adapter</span></code>.
|
||||
The down side of this approach is that runtimes are much slower when using
|
||||
this type. Set against that it can make debugging very much easier, certainly
|
||||
much easier than sprinkling code with <code class="computeroutput"><span class="identifier">printf</span></code>
|
||||
statements.
|
||||
</p>
|
||||
<p>
|
||||
When used in conjunction with the Visual C++ debugger visualisers, the
|
||||
value of a multiprecision type that uses this backend is displayed in the
|
||||
debugger just a builtin value would be, here we're inspecting a value of
|
||||
type <code class="computeroutput"><span class="identifier">number</span><span class="special"><</span><span class="identifier">debug_adapter</span><span class="special"><</span><span class="identifier">cpp_dec_float</span><span class="special"><</span><span class="number">50</span><span class="special">></span> <span class="special">></span>
|
||||
<span class="special">></span></code>:
|
||||
</p>
|
||||
<p>
|
||||
<span class="inlinemediaobject"><img src="../../../../debugger1.png" alt="debugger1"></span>
|
||||
</p>
|
||||
<p>
|
||||
Otherwise you will need to expand out the view and look at the "debug_value"
|
||||
member:
|
||||
</p>
|
||||
<p>
|
||||
<span class="inlinemediaobject"><img src="../../../../debugger2.png" alt="debugger2"></span>
|
||||
</p>
|
||||
<p>
|
||||
It works for all the backend types equally too, here it is inspecting a
|
||||
<code class="computeroutput"><span class="identifier">number</span><span class="special"><</span><span class="identifier">debug_adapter</span><span class="special"><</span><span class="identifier">gmp_rational</span><span class="special">></span>

|
||||
|
||||
The `debug_adaptor` type is used in conjunction with `number` and some other backend type: it acts as a thin wrapper around
|
||||
some other backend to class `number` and intercepts all operations on that object storing the result as a string within itself.
|
||||
|
||||
This type provides `numeric_limits` support whenever the template argument Backend does so.
|
||||
|
||||
This type is particularly useful when your debugger provides a good view of `std::string`: when this is the case
|
||||
multiprecision values can easily be inspected in the debugger by looking at the `debug_value` member of `debug_adapter`.
|
||||
The down side of this approach is that runtimes are much slower when using this type. Set against that it can make
|
||||
debugging very much easier, certainly much easier than sprinkling code with `printf` statements.
|
||||
|
||||
When used in conjunction with the Visual C++ debugger visualisers, the value of a multiprecision type that uses this
|
||||
backend is displayed in the debugger just a builtin value would be, here we're inspecting a value of type
|
||||
`number<debug_adapter<cpp_dec_float<50> > >`:
|
||||
|
||||
[$../debugger1.png]
|
||||
|
||||
Otherwise you will need to expand out the view and look at the "debug_value" member:
|
||||
|
||||
[$../debugger2.png]
|
||||
|
||||
It works for all the backend types equally too, here it is inspecting a `number<debug_adapter<gmp_rational> >`:

The next visualizer provides improved views of cpp_int: small numbers are displayed as actual values, while larger numbers are
|
||||
displayed as an array of hexadecimal parts, with the most significant part first.
|
||||
|
||||
Here's what it looks like for small values:
|
||||

||||

|
||||
|
||||
And for larger values:
|
||||
|
||||
[$../debugger5.png]
|
||||
|
||||
There is also a `~raw` child member that
|
||||
lets you see the actual members of the class:
