/**
 * Implementation for Excel DELTA() function.
 * <p>
 * <b>Syntax</b>:<br> <b>DEC2HEX  </b>(<b>number</b>,<b>places</b> )<br>
 * <p>
 * Converts a decimal number to hexadecimal.
 *
 * The decimal integer you want to convert. If number is negative, places is ignored
 * and this function returns a 10-character (40-bit) hexadecimal number in which the
 * most significant bit is the sign bit. The remaining 39 bits are magnitude bits.
 * Negative numbers are represented using two's-complement notation.
 *
 * <ul>
 * <li>If number &lt; -549,755,813,888 or if number &gt; 549,755,813,887, this function returns the #NUM! error value.</li>
 * <li>If number is nonnumeric, this function returns the #VALUE! error value.</li>
 * </ul>
 *
 * Places<P>
 *
 * The number of characters to use. The places argument is useful for padding the
 * return value with leading 0s (zeros).
 *
 * <ul>
 * <li>If this argument is omitted, this function uses the minimum number of characters necessary.</li>
 * <li>If this function requires more than places characters, it returns the #NUM! error value.</li>
 * <li>If this argument is non numeric, this function returns the #VALUE! error value.</li>
 * <li>If this argument is negative, this function returns the #NUM! error value.</li>
 * <li>If this argument contains a decimal value, this function ignores the numbers to the right side of the decimal point.</li>
 * </ul>
