The TI-83 Plus calculator features a function called "Frac" that converts decimal numbers into their fractional equivalents. For example, inputting 0.33333... and using the Frac function yields the result of 1/3. This function operates using algorithms that identify repeating decimals and convert them into fractions, similar to manual conversion methods. Understanding the underlying logic of the Frac function can enhance mathematical comprehension and calculator usage.
