|
||
|
|
<dd><p>The macro MPC_SET_X_Y is designed to serve as the body of an assignment
|
||
|
|
function and cannot be used by itself.
|
||
|
|
The <var>real_suffix</var> and <var>imag_suffix</var> parameters are the
|
||
|
|
types of the real and imaginary part, that is, the <code>x</code> in the
|
||
|
|
<code>mpfr_set_x</code> function one would use to set the part;
|
||
|
|
for the mpfr type, use <code>fr</code>.
|
||
|
|
<var>real</var> (respectively <var>imag</var>) is the value you want to assign to the
|
||
|
|
real (resp. imaginary) part, its type must conform to <var>real_suffix</var>
|
||
|
|
(resp. <var>imag_suffix</var>).
|
||
|
|
<var>rnd</var> is the <code>mpc_rnd_t</code> rounding mode.
|
||
|
|
The return value is the usual inexact value (see <a href="GNU-MPC-Basics.html#return_002dvalue">Return
|
||
|
|
Value</a>).
|
||
|
|
</p>
|
||
|
|
<p>For instance, you can define mpc_set_ui_fr as follows:
|
||
|
|
</p><div class="example">
|
||
|
|
<pre class="example">int mpc_set_ui_fr (mpc_t rop, long int re, double im, mpc_rnd_t rnd)
|
||
|
|
MPC_SET_X_Y (ui, fr, rop, re, im, rnd);
|
||
|
|
</pre></div>
|
||
|
|
</dd></dl>
