Re: TI-89: How to convert decimal sto fractions and vice versa
Right, I forgot the "exact()" command which
sometimes doesn't give me what I want. In your
illustrative case, the fraction 45.328 \approx
2765/61 might also be of interest.
A partial fraction for x is
1/(a+1/(c+1/(...)))=M/N, where M and N are
integers, and one simply chooses |x-M/N| to be
small.
