Stock market index movement always in full points rounded down

Without fail, every time the NYSE or other market indexes change for the day is reported on TV , the change is rounded down. For example, 32.85 is always 32. It’s never 33 (which is closer), it’s never “almost 33 points”, it always the lower full point.

Every reporter whether on a business channel or a jack-of-all trades on a local station consistently follows this rule as if it is beaten into their brains in journalism school and the most important rule in their paper’s style manual.

But if that is the case, why?

This is not true in my experience. I’ve heard reporters say “almost 33 points” or the like.

However, the reason why they would say “32 points” more often than “almost 33,” assuming they do, is simply because of the possible disconnect between viewing the number 32 on the screen and hearing the words thirty-three on the audio. This is a potential source of confusion over a fraction too small to be meaningful.
