Decimal To Fraction (alternative)

We're glad you came by, but you might find what you're looking for elsewhere. TI-Basic Developer is not the site it once was. While its information on commands and other calculator features remains almost second-to-none, its forum, archives, and even hosting service, Wikidot, have been decaying for years. The calculator community would love to see what you're working on, or help you in your next coding adventure, but TI-Basic Developer is no longer the place to do it. Instead, you should head over to Cemetech (primarily American) or TI-Planet (primarily international). Both are active, well-established forums with their own archives, chatrooms, reference material, and abundant coding tools and resources. We'll see you there, we hope.

:Ans→A:1→B
:While fPart(A
:10A→A:10B→B
:End
:{A,B}/gcd(abs(A),B

It starts by setting up a fraction with the input as the numerator and 1 as the denominator. After that, it multiplies both by 10 until the numerator is an integer, and then simplifies the fraction.

Error Conditions

• ERR:DATA TYPE is thrown if Ans is an imaginary or complex number
• ERR:DOMAIN is thrown if Ans has more than 11 digits after the decimal.
