The "Universal Device Poller" program on the SolarWinds server did not provide any further alternatives. I've also found a thread UnDP: Parsing Substrings? indicating that the *only* valid parse function is "(?<result>\d+)" (the variable "result" may differ) and that it must therefore process an integer. That doesn't get me to a float. It means, even assuming the SNMP string value *always* started with "0.", I wouldn't be able to distinguish "0.003" from "0.00003".
