<h2>12.9 Debugging the complex data type</h2>

<p><em><strong>Q</strong>: I cannot display in GDB the values of my variables of type
__complex__<small>...</small>.</em>

<br><p>
<p><strong>A</strong>:  Current versions of GDB don't support <code>__complex__</code>
variables.  A work-around is to manually cast them to a pair of
numbers.  For example, to access the real and imaginary part of a
variable <code>foo</code> declared <code>__complex__ double</code>, do this:

<pre> (gdb) print *(double *)&amp;foo
 $1 = 4
 (gdb) print *((double *)&amp;foo + 1)
 $2 = 6
</pre>
