If composite it gives you the smallest prime factor. It has good speed for its size: It tells you that 333667 is a prime in just 6 seconds! APRIME1: This is the second fastest prime checker that I have made. It has only 124 bytes, and it takes just a little more than two seconds to tell you that 333667 is a prime! APRIME2: This is the fastest prime checker. It uses a list ( LP ), that you need to install, either directly or by running PRCINST, before you can use the program. 10566779 is confirmed as a prime in just 8 seconds! |

| **frac1.zip** | 1k | 10-08-16 | | **Fractions** This file contains two programs and a textfile: CFrac1 is a small and fast program that reduces rational values. Its capacity is much better than the built in >Frac. The built in program has a largest denominator of 9999 and it can't handle a fraction like 8620/4311. CFrac1 can give correct answers for values of the numerator and denominator up to 40- 50 000. The answer is given both as improper fraction and as a mixed number, when the value is bigger than one. Can be used for quickly separating rational numbers from irrational, if the rational numbers don't have a too big fraction. Frac1 is a program aimed for bigger fractions where you input one term at a time. The numbers can have a numerator and denominator of ten digits. |

| **fracexpd.zip** | 2k | 06-04-12 | | **Fraction Expander Deluxe** This has been updated to be extremely small, ported to all TI's, and to be supremely fast.
