check_snmp calculate return value

[S]

Hello,

I do not see any option to alter the return value from an agent other 
than the rate-muliplier option or the offset option. Case in point: I 
have an agent where the value returned is 1787 but is in reality 17.87. 
It would be nice to have the option to perform other calculation on data 
presented to the monitoring system.

Thank-you for all your work on making monitoring happen and improving it.
