While TI and Casio scientific calculators are excellent for school, they have limitations when it comes to converting decimals to fractions.
For example, if a decimal corresponds to a fraction with a very large denominator, the calculator might just return the decimal back to you or encounter an overflow error. Furthermore, they do not show how the conversion was done, making it difficult for students to learn the underlying math concepts.
If the resulting fraction has a denominator larger than what the calculator can compute (typically > 9999), it will abort the fraction conversion and simply output the decimal again.
Newer Casio models have a recurring decimal feature (often Shift + the square/repeating key). On older models, you have to type the repeating sequence out to the end of the screen to trick the calculator into recognizing the pattern.

Most modern scientific calculators (like TI-84 or Casio fx-991) have dedicated fraction functions, but basic or older models may only display decimals.
On Casio calculators, S⇔D stands for Standard to Decimal. It toggles your answer between an exact fraction and a decimal approximation.
Calculators have a limit on how large a fraction
Yes, but you usually need to type the repeating sequence out to the edge of the screen so the calculator recognizes the pattern before you press the fraction convert button.
