TI-nspire CX rounding problem

Hey guys,
I have a TI-nspire CX and I'm wondering how to I can exactly get the non-rounded value of a decimal point on a graph to convert it into a fraction? I need to do that for trigonometry and my calculator always rounds it, so I can never get the good fraction? I need to be able to get a value let's say 0.666 not to stop there and to go to 0.6666666... forever to get 2\3 and not 333\500?
Thanks,
Kazoo
