My TI 84 won't convert my imaginary numbers to fractions. I typed in 1/(1+i) and it won't convert the answer to fraction form. It keeps saying Error Data Type

The TI-84 works with real fractions. It will not convert complex numbers to fractions.

You can convert the real and imaginary components to fractions separately. For your example, 1/(1+i) is .5-.5i. Converting .5 and -.5 to fractions, you get 1/2 + (1/2)i.

Because the TI84 does supports fractions in a funny way. Tap (3/4+1/2) then tap MATH and tap ENTER twice and you get the answer 5/4.
The TI 89 has a MODE called exact/approximate. In the exact MODE it does fractions; 3/4 + 1/2 = 5/4. In the approximate MODE it does decimals; 3/4 + 1/2 = 1.25

Repeating decimals into fractions

On the home page put 4.5 and press enter. Then hit "2nd" and "x" to get the "Math" window up. After that hit F5(Misc). Then hit "More". Finally, hit F1(Frac) and press enter. You should get the number (9/2). Repeat the same steps for 0.32.

Multiplication error(?) with repeating decimal place fractions.

You may have guessed right. The presence of the parentheses makes the content of the parentheses evaluated first. So there is a loss of precision.
On the Ti92 I do 7*(-1/7)+1 and find 0.
But with Floating mode set at 12 decimal digits I get
Then .142857142857.*(-7) + 1 gives 2E-14.
Try to calculate pi*(-1/pi) +1 or e*(1/e)+1.
Hope it answers your question.

When performing the calculations, put the fractions in parentheses. Then once you get your answer, press 2nd and Math (above the times button). Then press F5, MORE, and F1. It will have Ans Frac>. Then hit Enter and it'll change it to a fraction.
