* <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.
