The standard is to round a half upwards.
A half round file is good for work with any wooden project sand round corners
Not really because a semi-circle is a half-circle so only half of it is completley round.
If the fraction is less than half, round down. If the fraction is half or greater, round up.
4.5 already is rounded to the nearest half.

Hammer and chisel
To split a rock in half effectively, you can use a hammer and chisel. Place the chisel on the rock where you want it to split, then carefully strike the chisel with the hammer until the rock breaks along the desired line. Make sure to wear safety goggles and gloves to protect yourself from flying debris.

you round fractions by rounding up or down, you can decide to do this when you look at the numerator and decide if it is half of the denominator, if it is half or more than half, you round up. If it is less than half you round down. Another way you can round fractions is dividing the top number by the bottom number (with a calculator), then if the decimal part is 5 or more, round up! (if the decimal is less than 5, round down.)
No, a chisel is a cutting tool.
Carve
To the nearest half, one half

Assuming (as the cat is engineering) that you are using a round nosed cold steel chisel on a metal item. These were used to set in a dimple (dent) that would be used for decoration or its used to hammer in a channel for a liquid to move through similar to that inside a bearing. they were used before machinry to form a countersink that a retaining screw or rivet would sit into.
