10^x vs 10^y, order of magnitude compares the difference between x and y.
2 = 10^X
log(2) = X * log 10
0.301029995 = X
2 = 10^0.301029995
10 = 10^X
log(10)=xlog(10)
1=X
I was reading your post and other people post with my gf (she's an engineer) and we had a pretty bad laugh.
there's no need to take in account logarithms here.
the scientific notation of 2.0 is 2.0*10^0
the scientific notation of 9.0 is 9.0*10^0
the scientific notation of 10 is 1.0*10^1
So 10 is one order of magnitude greater than 9 or 2.
Order of magnitudes are integer numbers.
:thumbsup:
Thank God someone on here knows math!
The only application I am aware of where a 9.0 is an order of magnitude smaller than 10.0 is when measuring earthquakes.
It's pretty simple...
10 - 100 One order of magnitude larger
10 - 1000 Two orders of magnitude larger
So forth
and that someone is not you as you are confusing the logarithmic scale with order of magnitude.
Guys I hope all of you doesn't have a college degree in any scientific subject, or you should go back to your college and ask for your money back.
You don't need to be a mathematician. Even a CS understand this when he learns how floats are handled.
