2147483647.

What's the significance of this number? Wiki knows -

The number 2,147,483,647 is the eighth Mersenne prime, equal to (2^31) − 1. It is one of only four known double Mersenne primes.

The primality of this number was proven by Leonhard Euler, who reported the proof in a letter to Daniel Bernoulli written in 1772. Euler used trial division, improving on Cataldi's method, so that at most 372 divisions were needed. The number 2,147,483,647 may have remained the largest known prime until 1876.

Euler was a badass.

The reason that I bring this up is in light of the process which I'm doing for finally compiling usable test data for the IRS Form 1120 series of Software Development. On the 1120 Schedule M3, there's a few fields that they have values which are greater than three billion. I enter them, and after I tab out of the field, the number is magically changed from what I entered to 2147483647. As it turns out, the program correctly set the fields as integer types, and it had never happened until today that I entered a value in the integer field which surpassed its unstated limit. Making the change to handle the value is easy enough - just change the type from Int to Float and format the digit data format to prevent decimals from coming out (as the IRS doesn't parse them, and the formatting is done with num{zzzzzzzzzzzzzz9}), but this means that I'll have to keep an eye out for values that exceed the limit in the future and have to make changes as necessary. All things I wish I would have known sooner but that's what testing is for, right?

Hm, pretty crappy session today. Would have passed Alfashear if I had nailed the end triple jack correctly; instead, I got taken from a 78% to a 54% or something heinous. Oh well. At least I got one increase out of the day, and Hitch Hiker 2 is one of the nicer modestly increased charts in EX.
