<p>The node can specify multiple rules that will be applied in turn.</p>
<h3>Options</h3>
<p>The available operations are:</p>
<ul>
<li><b>Set</b> - set a property. The value can be a variety of different types, or
can be taken from an existing message or context property.</li>
<li><b>Change</b> - search &amp; replace parts of the property. If regular expressions
are enabled, the <b>replace with</b> property can include capture groups, for
example <code>$1</code>. Replace will only change the <b>type</b> if there
is a complete match.</li>
<li><b>Delete</b> - delete a property.</li>
<li><b>Move</b> - move or rename a property.</li>

<p>The "expression" option uses the <a href="http://jsonata.org/" target="_new">JSONata</a>
query and expression language. You can paste your data into <a href="http://try.jsonata.org/" target="_new">this site it</a>
to experiment and then use the expression back here.</p>

<p>A simple function node to remap numeric input values to another scale.</p>
<h3>Inputs</h3>
<dl class="message-properties">
<dt>payload <span class="property-type">number</span></dt>
<dd>the input payload <i>must</i> be a number. Anything else will try to be
parsed into a number and rejected if that fails.</dd>
</dl>
<h3>Outputs</h3>
<dl class="message-properties">
<dt>payload <span class="property-type">number</span></dt>
<dd>the output payload will always be a numeric type..</dd>
</dl>
<h3>Details</h3>
<p>Currently only does a linear scaling.</p>
<p><b>Note:</b> This only operates on <b>numbers</b>. Anything else will try to be made into a number and rejected if that fails.</p>
<p><i>Scale and limit to target range</i> means that the result will never be outside the range specified within the result range.</p>
<p><i>Scale and wrap within the target range</i> means that the result will essentially be a "modulo-style" wrap-around within the result range.</p>
