Also, if you are sending it to one of the dashboard nodes then you can do it in the node definition.

What complete code?  
If you mean using toFixed() then google for javascript toFixed to find how to use it.

This tells you how to do it in a dashboard node, courtesy of Paul Reed.

> If for example, you are displaying the value in a dashboard text node, you can always use angular filters to format the number. Adding {{msg.payload | number:1}} mph to the text node value format box will format a msg.payload from 18.31158 to 18.3 mph
