/**
 * Implementation for Excel HEX2DEC() function.
 * <p>
 * <b>Syntax</b>:<br> <b>HEX2DEC  </b>(<b>number</b>)<br>
 * <p>
 * Converts a hexadecimal number to decimal.
 * <p>
 * Number     is the hexadecimal number you want to convert. Number cannot contain more than 10 characters (40 bits).
 * The most significant bit of number is the sign bit.
 * The remaining 39 bits are magnitude bits. Negative numbers are represented using two's-complement notation.
 * Remark
 * If number is not a valid hexadecimal number, HEX2DEC returns the #NUM! error value.
