The automatic evalf logic in Function only calls evalf if every
argument is a float. It wasn't really designed for functions like
besselj where one argument is supposed to be an integer. It should
probably be updated to also automatically evalf if one argument is a
float and the rest are integers.
I wonder if anyone here can explain why some mathematical functions -
e.g. sin and gamma evaluate completely if given a floating point
argument, while others such as besselj(0,0.2) only evaluate completely
if .evalf() is used.
Is this behaviour intentional?
