[rrd-users] cdef + rpn

[Neil Calvert]

hi all

I have a problem converting a calculation to RPN and perhaps someone can
help.

The calculation I have to do is of the form :

( ( <octets per second> * 8 ) / <bandwidth in bits> ) * 100

to return a percentage of bandwidth used.

The two forms I've tried with CDEF are :

o,8,*,b,/,100,*

100,b,o,8,*,/,*


where o = octets, b = bandwidth in bits

Neither one gives the correct answer - can someone perhaps explain it
more clearly to me?

cheers

Neil
