Hello!
How can I calculate the log10 of a real number in Dark Basic? Is there any command or function to do that?
Thank you in advance.

No, there isn't. Create your own function. (Use either Newton-Raphson or Taylor method) Unless you only need an integer result, then it can be done easier.

Lol, kevil = kevin <> Kevin Picone.

It seems that the function uses the Newton-Raphson method (which is faster than using a Taylor polynomial in this case).

Edit: Though that looks like it could be my code (my coding style )
