I am attempting to read formula strings from an array of clusters. No problem, works great. Now I want to evalute the string formulas to determine if the values are greater or less than what is specified in the formula ( BatteryVoltage < 5.0 ). The current string to formula evaluate funtions do not handle "<>&|" operators. Any ideas that won't cost an arm and a leg???

Hi lcarner
One thing you can try is evaluating those values using the <>& nodes in LabVIEW. You can take the output values of the Formula Parsing VIs and evaluate them using the native LabVIEW comparison nodes.

I use the open source library muParser (http://muparser.beltoforion.de/) to evaluate mathematical expressions in my project Open Dyno www.opendyno.com.

A new LabVIEW API for muParser is available on LAVA: https://lavag.org/files/file/295-lv-muparser/
