- * <p>Implementation for Excel QUOTIENT () function.<p/>
- * <p>
- * <b>Syntax</b>:<br/> <b>QUOTIENT</b>(<b>Numerator</b>,<b>Denominator</b>)<br/>
- * <p/>
- * <p>
- * Numerator is the dividend.
- * Denominator is the divisor.
- *
- * Returns the integer portion of a division. Use this function when you want to discard the remainder of a division.
- * <p/>
- *
- * If either enumerator/denominator is non numeric, QUOTIENT returns the #VALUE! error value.
- * If denominator is equals to zero, QUOTIENT returns the #DIV/0! error value.
