ITHPRIME (Index,Max)


  • is any real number
  • is the maximum limit
    • ITHPRIME(), returns the ith prime.

Description

ITHPRIME(Index,Max)

For Example,

ITHPRIME(4,25) returns 7 as a result.

  • ITHPRIME(Index,Max) calculates the  th prime number from the Prime Number Series (2,3,5,7,11,13,17..........) and displays as an output, if it is less than   value.
  •   and   should be real numbers, else Calci displays #NULL error message.
  •   should be > 2.
  • If   is less than the   prime number value, Calci displays #NULL error message.

Examples

Consider the following example in Calci, that shows the use of ITHPRIME function:

3 6
6 30
=ITHPRIME(A1,A2): Calculates the 3rd prime number in the series, checks if it is < 6. 
Displays 5 as a result. =ITHPRIME(B1,B2): Calculates the 6th prime number in the series, checks if it is < 30.
Displays 13 as a result.
