<p>Use the <b>div</b> <glossary tag="operator">operator</glossary> to do integer division.</p><p/><p><b>Parameters:</b></p><p>The <i>number</i> is a number, or an <glossary tag="expression">expression</glossary> that <glossary tag="evaluate">evaluates</glossary> to a number, or an <glossary tag="array">array</glossary> containing only numbers.</p><p/><p>The <i>divisor</i> is any non-zero number. If the <i>number</i> is an <glossary tag="array">array</glossary>, the <i>divisor</i> is either a non-zero number or an <glossary tag="array">array</glossary> containing only non-zero numbers.</p><p/><p><b>Comments:</b></p><p>If the <i>number</i> to be divided is an <glossary tag="array">array</glossary>, each of the <glossary tag="array">array</glossary> <glossary tag="element">elements</glossary> must be a number. If an <glossary tag="array">array</glossary> is divided by a number, each <keyword tag="element">element</keyword> is divided by the number. If an <glossary tag="array">array</glossary> is divided by an <glossary tag="array">array</glossary>, both <glossary tag="array">arrays</glossary> must have the same number of <glossary tag="element">elements</glossary> and the same dimension, and each <keyword tag="element">element</keyword> in one <glossary tag="array">array</glossary> is divided by the corresponding <keyword tag="element">element</keyword> of the other <glossary tag="array">array</glossary>.</p><p/><p>If an element of an array is empty, the <b>div</b> <glossary tag="operator">operator</glossary> treats its contents as zero.</p><p/><p>The expression<code> dividend div divisor </code>is equivalent to<code> trunc(dividend/divisor)</code>.</p><p/><p>If <i>dividend</i> can be divided evenly into <i>divisor</i>, the <glossary tag="expression">expression</glossary> <code>dividend div divisor</code> is equal to<code> dividend/divisor</code>.</p><p/><p>Attempting to divide by zero causes an execution error.</p><p/><p><code/><b>Note:</b><code/> While using non-integer <i>number</i> and <i>divisor</i> usually produces sensible results, mathematically, integer division is generally defined as a function over the integers, and the results using non-integers may not consistently be what you expect.</p><p/><p><b>Changes:</b></p><p>The option to divide arrays was introduced in version 1.1. In previous versions, only single numbers could be used with the <b>div</b> <glossary tag="operator">operator</glossary>.</p>
