Do SNMP4J have any util method that change octeString to float?

I have get the query result using SNMP4J ,and I know the result is Opaque data type from SNMP-NET. So I wander whether SNMP4J have any util method that change octeString to float?

No. but this might help:

In general using Opaque is not recommended. Better use an Integer32 with DISPLAY-HINT for the scale.
