This is a calculator for the Collatz Conjecture, also known as the 3n+1 problem, it is a famous and unsolved problem It was first proposed by German mathematician Lothar Collatz in 1937. The conjecture is quite simple to state, take any positive integer number. If number is even, divide it by 2.If it is odd, Multiply by 3 and add 1 here are the rules for this calculator the chart may change position automatically so I am sorry, I do not know how to fix it press the flag button twice to restart this calculator again. obviously it is gonna have a limit to the size of the number. if you try to put other kinds of characters along with a number, it will just show 0. if you do not use actual digits as a number to chose, it will just stop this bad boy can even do the calculation for numbers with decimal value! but it may be misleading as it will keep multiplying by 3 and adding 1 due to the code and It would also try negative numbers, but it would keep calculating until the list reaches maximum capacity tell me if something is wrong with this calculator in the comments the rest of the Collatz conjecture's information is here, copy it onto google chrome to go to it's wiki page, I do know that the wiki can not be trusted much, but which website do I need to choose? I do not need to get it from Yahoo or something? https://en.wikipedia.org/wiki/Collatz_conjecture
