Hi all.

I have some prob with log function.
The code below is not working, it returns a false value.
The value is not same with what I calculate using scientific calculator.

Using my program:
N=2
Na=1
log(N/Na)=0.6931

Using scientific calculator:
N=2
Na=1
log(N/Na)=0.30102999566

Code:

Yes, I had that same problem once...
In Visual Basic, LOG function is returning a value of natural logarithm (base2), whereas in math LOG specifies Base10 logarithm (or at least I think so). Now, in scientific calculator, you might have noticed LN button, just above the LOG button. If you do that function, you will get the value you want. So, in order to get the numbers you need, use this code or put it in a function:


This should give you the values you need, so your code might look something like this:

Hi. It is must be a same result. Because mathemathics didn't change. Check your code.
