The probability of it being + ; greater than the max is always strictly less than 1/2. + ; + ; This is the same idea but in base 2^30 (1073741824). The + ; first digit's weight is (2^30)^2 = 1152921504606846976, + ; similarly to how in our base 10 example, the first digit's + ; weight is 10^2 = 100. In the base 10 example we first divide + ; the target number 348 by 100, taking the ceiling, to get 4. + ; Here we divide by (2^30)^2 instead, taking the ceiling too. + ; + ; The math is a bit obscured by the fact that we generate + ; the digits as negative, so that the result is negative as + ; well, but it's really the same thing. Changing the sign of + ; every digit just changes the sign of the result. + ; + ; This method works for n up to (2^30)^2*(2^31-1) which is + ; 2475880077417839045191401472 (slightly under 91 bits). That + ; covers the 64-bit range comfortably, and some more.
