There's nothing to discuss. 0.5 is rounded up to 1 by convention.

Anything below 0.5 is rounded down.

That isn't expressed in the OP pic. 1 and 2 can't be proven to be different relations. You fucked up, OP.

False, for any x where 0.5<x<0.6, statements (1) and (2) are mutually exclusive because the former will return '1' and the latter will return 'x'. There are infinitely many numbers between 0.5 and 0.6.
There are infinitely many cases where (1) and (2) are proven to be different relations.

1) Is the only case that makes linguistic sense. "Equals about" implies that the closest integer to x is 1, which is not true in the second case.

That was not expressed in OP pic. In fact, for any x where 0.5<x<0.6, statements (1) and (2) will both return '1'. Prove me wrong, using logic and only the information provided in OP pic. Pro tip, you can't.

x equals 5.5
(1) .5<x, so return 1
(2) the hypothesis is vacuously false, so return 1

Here is a simpler explanation for your feeble mind:
by the laws of (2), if x<0.6, then ???. This statement cannot be proven to be false, so by law of excluded middle, it must be true. True statements return 1. Thus, all x round to 1.

According to Occam's Razor, the simplest explanation is the most likely. In both scenarios, at least half of the interval is rounding to one, with no explicit instructions for the rest of the interval. The simplest explanation is that everything >0 rounds to 1, because both (1) and (2) are the ceiling function.

In your scenario, 0.1 rounds to 1.
>>10851189
But they have different conditions. And the OP asks (1) or (2), meaning they are mutually exclusive.

yes, .1 should round to 1. And they do not have different conditions, they are exactly the same. And mutually exclusive doesn't mean shit. It could be if (1) doesn't satisfy the rounding condition, then if it is irrational it rounds up, and down for irrational. and (2) could mean the opposite. So the simplest explanation is everything rounds up, except possibly 0.
