86 billion.

Question

hello, im trying to find the factorial for 86 billion, no calculator would work, so i wrote a factorial function in java. i got the error saying integer value too large. i dont know how to get java to do it.

Answer 1

It's not Java fault. Basically integer is only 32bit number which means the biggest number you can save in is 2^32. Please refer to docs about saving larger number =)

Use BigInteger class but 86 billion is very huge number.

Answer 4

How exact do you need your number? Fully as a number to use it further or do you just need to have a specific accuracy? Is printing it enough?

Answer 5

it timed out at 860.
somebody ask the devs to increase page symbol limit because it wont print the entire thing to the page.
