## Description
|
|||
|
|
<section id="description"> <dfn>余数</dfn>运算符<code>%</code>给出了两个数的除法的余数。 <strong>例</strong> <blockquote> 5％2 = 1因为<br> Math.floor（5/2）= 2（商数） <br> 2 * 2 = 4 <br> 5 - 4 = 1（剩余） </blockquote> <strong>用法</strong> <br>在数学中，通过检查数字除以<code>2</code>的余数，可以检查数字是偶数还是奇数。 <blockquote> 17％2 = 1（17为奇数） <br> 48％2 = 0（48为偶数） </blockquote> <strong>注意</strong> <br> <dfn>余数</dfn>运算符有时被错误地称为“模数”运算符。它与模数非常相似，但在负数下不能正常工作。 </section>
