<![CDATA[Calculating a value in page]]>Hello, I have to calculate capacity for a chiller, and I want to know if is possible to calculate this without creating a meta point. I have the following formula:
ChCapacity = (CHW_Flow * (CHW_Return_Temp - CHW_Supply_Temp)*1.8)/24

It is possible to calculate this directly on web page and display the result somewhere in page or I have to create a meta point.

e.g.

 <div id="13688a40-881d-4956-b42a-14362bbe73ef" style="position: absolute; left: 480px; top: 142px;" ng-bind="(CHW_Flow * (CHW_Return_Temp - CHW_Supply_Temp)*1.8)/24"></div>

However I assume those are actually point values in which case it will probably be more like

 <div id="13688a40-881d-4956-b42a-14362bbe73ef" style="position: absolute; left: 480px; top: 142px;" ng-bind="(flowPoint.value * (returnTempPoint.value - supplyTempPoint.value)*1.8)/24"></div>

You can also wrap expressions with curly braces {{ }}

<div>
{{ (flowPoint.value * (returnTempPoint.value - supplyTempPoint.value)*1.8)/24 }}
</div>
