Math/Not math

mood: confused confused
So my computer has apparently lost the ability to do math, or is perceiving some subtle arithmetic nuances that I've missed. First, I tried adding the following, on Koncalculator2:
2627 + 1292.61 = 3919.60999999999
Next, I abandoned it for the Calculator application in OS X. It added those numbers according to the mathematic laws with which I have become accustomed, with a result of 3919.61. Then I attempted to add 400, which yielded a result of 4319.610000000001.

I'm afraid I may have broken the universe. Oops.

I'm a bit fuzzy on the details, but it looks like an internal rounding error. Has something to do with the way it stores the fractional part.

Me too, but if it's broken for me, it's broken for everyone.

it was prolly me
i exceeded lightspeed, so the universe got a divide by zero error when computing the slope of spacetime at the point where i existed because my mass was infinite
