ITHPRIME(i, n)
where,
- is any real number
- is the maximum limit
is any real number
is the maximum limitITHPRIME() calculates the 'ith' prime number less than a maximum value 'n'.
Description
ITHPRIME(i, n)
For Example,
ITHPRIME(4,25) returns 7 as a result.
- ITHPRIME() 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 .
- and should be real numbers, else Calci displays #NULL error message.
- should be > 2.
- If is less than the th 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.
