Fonction Log()

[azarus]

I have tried:
showmessage str$ (log(2.718281))
I obtain 1.3132 => Log() is not natural logarithm :ln(e)=1
I have tried:
showmessage str$ (Log(10))
I obtain 2.39 => Log() is not based on 10
It seems that with Fnxbasic ln(x)= Log(x-1).How is it possible ??

The function log without parameter will return the log of xp1 wich is the natural log of (X+1). I will fix it in the new version.
To get the natural log do log(2.7-1) or log(2.7,2.7)
