Re: precision on all calcs



Maybe you should do some research before you start flaming me. The TI-92 DOES
GIVE EXACT VALUES!! For example, if you enter sin(45), it says sqrt(2)/2 in
the answer line.

If you folks would pay attention in your math classes instead of playing
these silly games, you would know the answer.  Pi is an irrational number.
Yet you would like a computer algorithm that returns an exact value for the
sin (1).  That's rich!!!
