Prime in Prime Out
I developed a prime input program in Python where atleast one of the three outputs should have an outcome of a prime number! If for some reason no outputs produce, than it must be either a big number imputed and the outcome is off by under 100 or 2.
I was trying to forecast Mersenne Primes again, yet now it does, however at times forecast prime numbers. I know this is not a big deal, because we have code which can yield primes perfectly. I did obtain a prime number from the largest prime root found which contributed to the largest world record Mersenne Prime Number. Here is the code if you are curies: Code:
print('''Enter a prime number to retrieve a prime number, occasionally all 3 will be off, but more than likely one output should be prime''') while True: p = int(float(input("Enter a prime number: "))) if p == 0: print(False) else: print(p) print((round(4*(p*(.49999999911781146)+p)+(.49999999911781146))+1),'''Prediction of prime number!''') print((round(4*(p*(.49999999911781146)+p)+(.49999999911781146))+13),'''Use this one for LARGE NUMBERS prediction of prime number!''') print((round(4*(p*(.49999999911781146)+p)+(.49999999911781146))+7),'''Last ditch Prime prediction!''')

2233332341 as input does not pruduce any prime. Do you have any idea what number is "too big", where's the limit?

I believe the first prime p for which all three numbers are not only composite, but for which all numbers within 100 of each are composite is p = 64516043. I imagine these primes should have density 1.
