    • isPrime

      public static boolean isPrime(BigInteger number)
      Checks if a given BigInteger is prime. The certainty of this check is always 100%
      Parameters:
      number - the number to check
      Returns:
      whether or not this number is a prime

    • random

      public static Number random(Number lower, Number upper, boolean inclusive, ThreadLocalRandom random)
      Computes a random number between the two given bounds

      The return type is related to the parameter types in the following way :

      • Two bounds of the same type will return a result of the same type
      • If one of the bounds is a BigDecimal, so will be the result
      • If one of the bounds is a BigInteger and the other is a Double, the result will be a BigDecimal
      • If one of the bounds is a BigInteger and the other is a Long, the result will be a BigInteger
      • Otherwise (i.e one of the bounds is a long and the other a double), the result will be a double
      Parameters:
      lower - the lower bound
      upper - the upper bound
      inclusive - whether the bounds are exclusive or not (skript-parser defaults to true in its implementation)
      random - the ThreadLocalRandom instance used
      Returns:
      a random Number between the two given bounds

    • randomBigInteger

      public static BigInteger randomBigInteger(BigInteger lower, BigInteger upper, ThreadLocalRandom random)
      Parameters:
      lower - the lower bound
      upper - the upper bound
      Returns:
      a random BigInteger between lower (inclusive) and upper (exclusive)

    • randomBigDecimal

      public static BigDecimal randomBigDecimal(BigDecimal lower, BigDecimal upper, ThreadLocalRandom random)
      Parameters:
      lower - the lower bound
      upper - the upper bound
      Returns:
      a random BigDecimal between lower (inclusive) and upper (exclusive)

    • getCachedPrimes

      public static ArrayList<Integer> getCachedPrimes()
