/**
 * Implementation for Excel IMAGINARY() function.
 * <p>
 * <b>Syntax</b>:<br> <b>IMAGINARY  </b>(<b>Inumber</b>)<br>
 * <p>
 * Returns the imaginary coefficient of a complex number in x + yi or x + yj text format.
 * <p>
 * Inumber     is a complex number for which you want the imaginary coefficient.
 * <p>
 * Remarks
 * <ul>
 * <li>Use COMPLEX to convert real and imaginary coefficients into a complex number.</li>
