Re: something like dB


Hi,

Defining an upvalue:

dB/:Times[0,dB]=1

worked for me with 5.1, and 0 dB does indeed then avaluate to 1.

However, I am not sure it is a good idea to do that sort of thing 
because it could  lead to confusion. I would always use CircleTimes to 
define a multiplication that wasn't!
