RANDARRAY 関数

RANDARRAY 関数は、ランダムな数値の配列を返します。

<p>RANDARRAY関数は、乱数の配列を返します。 ユーザーは、行と列の数、最小値と最大値、および整数またはデシマル値を返すかどうかを指定できます。</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%;">引数</th> <th style="width: 10%;">必須</th> <th style="width: 70%;">説明</th> </tr> <tr> <td>[rows]</td> <td>N</td> <td>返される行の数</td> </tr> <tr> <td>[columns]</td> <td>N</td> <td>返される列の数</td> </tr> <tr> <td>[min]</td> <td>N</td> <td>返される最小数</td> </tr> <tr> <td>[max]</td> <td>N</td> <td>返される最大数</td> </tr> <tr> <td>[whole_number]</td> <td>N</td> <td>整数またはデシマル値を返します。整数の場合はtrue、デシマル値の場合はfalseです。</td> </tr> </tbody> </table> <p><strong>注意:</strong></p> <ul> <li>RANDARRAY関数は、<code>allowDynamicArray</code>がtrueの場合にのみ有効です。</li> <li>RANDARRAY関数は配列を返しますが、それが数式の最終結果である場合、スピルとなります。</li> <li>行または列の引数を入力しない場合、RANDARRAYは0〜1の単一の値を返します。</li> <li>最小値または最大値の引数を入力しない場合、RANDARRAYはそれぞれ0と1にデフォルト設定されます。</li> <li>最小数の引数は最大数より小さくする必要があります。そうでない場合、RANDARRAYは#VALUE!エラーを返します。</li> <li>whole_number引数を入力しない場合、RANDARRYはデフォルトでFALSEまたはデシマル値になります。</li> </ul>
