Usage Notes

By default, incoming variables to the expressions that you create in this node are treated as string variables. If a string input does not suit your needs, you can use the DataFlux tointeger function to specify incoming variables as numeric. Here is an example of an expression that uses the tointeger function:

if tointeger(varname) > 10
dosomething
else
dosomethingelse
