A prime number is a positive integer which has exactly two distinct positive divisors, 1 and itself. With that definition 0 is not prime since all integers divide 0, nor 1 which has only one positive divisor. The prime numbers less than 100 are:

{2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97}

This calculator provides a list of prime numbers

- When the first radio button is checked, the primes are provided by rank, ie all primes from the 1000th to the 2000th
- When the second radio button is checked, the primes are provided by value, ie all primes from 1000 to 2000. In that case you may get the rank of these primes checking the box "print rank too"
