* <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. | |
