Hi,
I've noticed that ROOT doesn't understands the functions atanh(x), asinh(x)
(and maybe more) from the command line or inside scripts.
When I try interactively for example I get:
<cueball-clued0> root

Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.

Same I get from inside a script macro (the function is unknown) although I
have
loaded the <cmath> library. It's kind of strange that the "sinh(x)" function
is know
but not the inverse of it.
Have those functions somehow been removed from ROOT?
The corresponding TMath::ASinH(x) and TMath::ATanH(x) functions work ok.
Stelios.
