<p>The <b>COMPLEX</b> function is one of the engineering functions. It is used to convert a real part and an imaginary part into the complex number expressed in a + bi or a + bj form.</p>
<pstyle="text-indent: 50px;"><b><em>real-number</em></b> is the real part of the complex number.</p>
<pstyle="text-indent: 50px;"><b><em>imaginary-number</em></b> is the imaginary part of the complex number.</p>
<pstyle="text-indent: 50px;"><b><em>suffix</em></b> is an indicator of the imaginary part of the complex number. It can be either "i" or "j" in lowercase. It is an optional argument. If it is omitted, the function will assume <b><em>suffix</em></b> to be "i".</p>
<p>The values can be entered manually or included into the cell you make reference to.</p>
