RANDARRAY 函数

RANDARRAY函数返回一个随机数数组。

<p>RANDARRAY函数返回一个随机数数组。用户可以指定要填充的行和列的数量,最小值和最大值,以及返回整数或十进制值。</p> <pre><code class="hljs js language-js">=RANDARRAY(rows?, columns?, min?, max?, whole_number?) </code></pre> <table border="1" style="border-collapse: collapse;width:90%;"> <tbody> <tr> <th style="width: 20%;">参数</th> <th style="width: 10%;">必需</th> <th style="width: 70%;">描述</th> </tr> <tr> <td>[rows]</td> <td>否</td> <td>要返回数据的行数</td> </tr> <tr> <td>[columns]</td> <td>否</td> <td>要返回数据的列数</td> </tr> <tr> <td>[min]</td> <td>否</td> <td>随机数的最小值</td> </tr> <tr> <td>[max]</td> <td>否</td> <td>随机数的最大值</td> </tr> <tr> <td>[whole_number]</td> <td>否</td> <td>返回整数或浮点数:整数则为true,浮点数为false。</td> </tr> </tbody> </table> <p><strong>注意:</strong> </p> <ul> <li>RANDARRAY 函数仅在<code>allowDynamicArray</code>为true时有效。</li> <li>RANDARRAY 函数将返回一个数组,如果该数组是公式的最终结果,则将溢出。</li> <li>如果没有行或列参数,RANDARRAY将返回0到1之间的一个值。</li> <li>如果不提供最小值或最大值参数,则RANDARRAY将分别默认为0和1。</li> <li>参数最小值必须小于最大值,否则RANDARRAY将返回#VALUE!错误。</li> <li>如果不输入Whole_number参数,则RANDARRY将默认为FALSE,即浮点数。</li> </ul>
