import "math/big" func main() { num := big.NewInt(123456789) if num.ProbablyPrime(10) { fmt.Println("The number is probably prime") } else { fmt.Println("The number is definitely composite") } }
import "math/big" func main() { num := big.NewInt(999999999999) if num.ProbablyPrime(5) { fmt.Println("The number is probably prime") } else { fmt.Println("The number is definitely composite") } }In this example, `ProbablyPrime` is used to test if the number 999999999999 is a prime number. However, this time we have used only 5 iterations for the Miller-Rabin test, meaning that the function will run only 5 tests and return false if the number fails any of the tests. Therefore, the `math/big` package in Go provides support for various mathematical operations involving big integers, including functions for prime number operations like `ProbablyPrime`.
