The math operations will only happen to numbers (via the SNMP return type).
The inclusion of a ; means it is returning as a string.

You might try using the [UPS-MIB
OIDs](http://www.oidview.com/mibs/0/UPS-MIB.html) and see if the frequency
endpoint there returns a cleaner value first.

That's just bad/lazy MIB design that defeats the purpose of SNMP.
