Division (/)

If either of the operands is a string, an attempt is made to convert the string to a number.

For example, the following line of code



var resultOfDiv = 42 / 7;

would result in the value of 6 being stored in the variable resultOfDiv.



<html>
    <script language="JavaScript">
    <!--
    aString = new String("168");
    x = aString / 14;
    document.write("x = ",x);
    -->
    </script>
</html>

The divide operator, like the multiply operator, has special behaviors for special values:

If the operands are numbers, regular arithmetic division is performed, meaning that two positives or two negatives equal a positive, whereas operands with different signs yield a negative. If the result is too high or too low, the result is either Infinity or ?nfinity.

If either operand is NaN, the result is NaN.

If Infinity is divided by Infinity, the result is NaN.

If Infinity is divided by any number, the result is Infinity.

Division of a non-infinite number by 0 always equals NaN.

If Infinity is divided by any number other than 0, the result is either Infinity or ?nfinity, depending on the sign of the second operand.
