LISTPRIMES(max,min,i)

• $max$ is the upper limit.
• $min$ is the lower limit and i is the $i_{th}$ position of a prime number.

Description

• This function is listing the set of prime numbers for the given set of numbers.
• A prime number is a natural number, it can be divided, without a remainder, only by itself and by 1.
• For e.g. the number 11 is a prime, because 11 is divided by 1 and 11 without any remainder.
• But 6 is not prime, because 6 can be divided by 1,2,3 and 6. Such numbers are called composite numbers.
• Also the number 0 and 1 are neither prime nor composite.
• In $LISTPRIMES(max,min,i)$, gives the list of prime numbers between the range $max$ and $min$.
• $max$ is the upper limit value and $min$ is the lower limit value
• And $i$ is the position of the prime number value. $i$ value is optional.
• Suppose we are not giving the ith value, it will show all the prime numbers in given range.
• This function will give the result as error when

1. any one of the argument is nonnumeric.
2. $max<min$ or $i$ is the beyond the range number of prime numbers
3. $max$ or $min<0$.

Examples

1. LISTPRIMES(20,11)=11 13 17 19
2. LISTPRIMES(20,11,3)=17
3. LISTPRIMES(150,130)=131,137,139,149
4. LISTPRIMES(10,-1)=2 3 5 7
5. LISTPRIMES(-10,1)=Null
6. LISTPRIMES(90,70)=71 73 79 83 89
7. LISTPRIMES(90,70,4)=83
8. LISTPRIMES(90,70,6)=Null
