<p>将数值映射为另一个区间的数值</p>
<h3>输入</h3>
<dl class="message-properties">
<dt>payload<span class="property-type">数值</span></dt>
<dd>有效荷载<i>一定</i>得是一个数值. 否则则会映射失败。</dd>
</dl>
<h3>输出</h3>

<h3>详细</h3>
<p>该节点将线性缩放所接收到的数值。在默认情况下,结果不限于节点中定义的范围。</p>
<p><i>缩放并限制到目标范围</i>表示结果永远不会超出目标范围内指定的范围。</p>
<p><i>在目标范围内缩放并折叠</i>表示结果将会被限制(折叠)在目标范围内。</p>
<p>例如输入0-10映射到0-100。</p>
