If I want determine the relative position between the point(0.7,0.3) and the
triangle with vertices(-1,0)(1,0)(0,1) precisely, what should I do?

A said, you can use a fully exact kernel.

A cheaper solution is to use the Inexact constructions exact predicates kernel
with a number type that can represent your input.

e.g. if instead of

point(0.7,0.3) and the
triangle with vertices(-1,0)(1,0)(0,1) 

you have

point(7,3) and the
triangle with vertices(-10,0)(10,0)(0,10) 

everything will work perfectly.
