Hi, regarding the below, is it possible to increase precision for this past
(15) ? Im a little bit confused.... are you saying that a float set to the
default
precision will not return the accurate result but specifying the precision
will?
Also you mentioned a non float expression will return the correct value, but
when I try ; x = nsimplify("1.4142"), evalf()
It returns only an error message?
