Hi,
I've just noticed in some oldish code that gretl accepts the ln()
function which isn't documented (nor syntax colored).
? eval ln(2)
0.69314718
? eval log(2)
0.69314718
Is this a fully valid alias or actually a deprecated function? (In which
case a deprecation warning might be useful.)
thanks,
sven

Well, I would say that nothing is offically deprecated unless it's
mentioned at http://gretl.sourceforge.net/Backward.html and on that
criterion "ln" is not deprecated. But neither is it recommended. Let
sleeping dogs lie?

Fine with me, but speaking of sleeping dogs I was a bit surprised by
this behavior:
? scalar log = 3
? eval log(log)
1.0986123
I didn't know you could have an identifier which is identical to a
function name. (Not a command name!)
thanks,
sven
