ISPRIME(int)
- is any number
is any numberDescription
- This function is one of the group in ISFUNCTIONS.
- The IS FUNCTION is also known as data information functions, data inspection functions or data-testing functions.
- ISPRIME function is used to test the given number is prime or not.
- This function gives the result as TRUE when the given value is prime otherwise this function gives th result as FALSE.
- 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.
- Also the number 0 and 1 are neither prime nor composite.
ZOS Section
- The syntax is to find whether the given number is prime in ZOS is .
- is any number.
- For e.g.,ISPRIME(5.1)= true.
.
Examples
- =ISPRIME(2)=TRUE
- =ISPRIME(7)=TRUE
- =ISPRIME(105)=FALSE
- =ISPRIME(1)=TRUE
- =ISPRIME(-2)=FALSE
- =ISPRIME(0)=FALSE
- = ISPRIME(5.1) = FALSE
