I need to get the common logarithm of a variable. Looking over the internet, I see examples that *should* work, but don't.

This what I started out with:

float lg;
float sg;

sg = Log10(lg);

I got this:
[BCC32 Error] Unit1.cpp(77): E2268 Call to undefined function 'Log10'

On another site I saw where the variables should be of type, Extended.

When I typed in Extended sg; I expected to see the Extended in boldface(Extended) but it wasn't. I also got the same error msg as before.
Can someone clear this up for me?
Thanks,
Paul

Never mind I should have used log10() instead of Log10()!
