Log In Calci!

I did like to know how the standard Windows calculator calculates the
'log' of any number (not 'ln') when it is in the scientific mode. It's
definitely not log(number) since 'ln' is calculated using the formula
log(number). So how is the 'log' of a number calculated? Any idea?

Thanks,

Arpan

Are you asking what button to press to get the log or about
the mathematical process behind the log button? If it is the
latter then you probably need to talk to Microsoft. Alternatively,
if you're patient, you could debug calc.exe . . .
 
I am talking about the latter - the mathematical process behing the log
button. The first solution isn't viable; so please tell me how to debug
calc.exe.

Thanks,

Debugging a program is only feasible if you have the following:
- In-depth knowledge about the processor mnemonic instruction set.
- A good symbolic debugger. Debug.exe is not symbolic and using
it for this job is equivalent to sweeping all runways of an airport
with a toothbrush.
- An enormous amount of time and patience.

It would be much faster for you to consult some text books
on algorithms used to compute various mathematical
functions, then writing your own program to do the job.
This is not a Windows issue at all so I strongly recommend
that you find a suitable newsgroup. You might find out from
them, for example, that the ratio of ln(x) to log(x) is ln(10).

Then it's not my cup of tea!

I guess, you are right, Pegasus.
