Hi,

I'm doing some easy calculations to normalize some values. This looks like
this:

x=mean(a+b+c+d ...)
a=a-x
b=b-x
c=c-x
d=d-x
...
mean(a+b+c+d ...) ---> Should now be 0!
However, I'm getting results like -2.315223e-18
This is really near to 0 but not very aesthetic.

Can I prevent this? Or is this behaviour desired?
Thank you very much!
Burtan
