|
<p>The complex functions expect arguments of type <code>mpc_t</code>.
|
||
|
|
</p>
|
||
|
|
<p>The GNU MPC floating-point functions have an interface that is similar to the
|
||
|
|
GNU MP
|
||
|
|
integer functions. The function prefix for operations on complex numbers is
|
||
|
|
<code>mpc_</code>.
|
||
|
|
</p>
|
||
|
|
<a name="index-User_002ddefined-precision"></a>
|
||
|
|
<p>The precision of a computation is defined as follows: Compute the requested
|
||
|
|
operation exactly (with “infinite precision”), and round the result to
|
||
|
|
the destination variable precision with the given rounding mode.
|
||
|
|
</p>
|
||
|
|
<p>The GNU MPC complex functions are intended to be a smooth extension
|
||
|
|
of the IEEE P754 arithmetic. The results obtained on one
|
||
|
|
computer should not differ from the results obtained on a computer with a
|
||
|
|
different word size.
