rounding When to Round Up
Rounding up means that we increase the terminating digit by a value of 1 and drop off the digits to the right. If the next place beyond where we are terminating the decimal is greater than or equal to 5, we round up. For example, if we round 5.47 to the tenths place, it can be can be rounded up to 5.5.


When to Round Down
If the number to the right of our terminating decimal place is 4 or less (4, 3, 2, 1, 0), we round down. This is done by leaving our last decimal place as it is given and discarding all digits to its right. For example, if we round 6.734 to the hundredths place, it can be rounded down to 6.73.

approssimare per difetto se la temperatura è, per esempio, 36.1. Allora si inserisce 36.0
approssimare per eccesso se la temperatura è, per esempio, 36.3, quindi si inserisce 36.5
In realtà vorrei sapere se il verbo "to approximate" viene utilizzato oppure se è meglio "round down" e "round up". Ho trovato spesso "approximation" ma vorrei usare il verbo e non il sostantivo. Grazie :)

approssimazione La frase italiana non è chiara; si arrotonda a 0.2 ogni valore compreso (o uguale) fra 0.15 e 0.24"; si arrotonda a 0.3 ogni valore compreso (o uguale) fra 0.25 e 0.34

the only other thing I can provide is that it's about the body temperature. It's in a table so there isn't anything else, I am afraid.

More context please. It would help me understand how to work "rounding down" into the sentence. Thanks!
