| * <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. |
