11 paź 2023 · Rounding number is the process of approximating the number to its closest value. It involves reducing the number of significant digits while retaining the general magnitude or size of the original number. The result of rounding is less accurate than the original number but simplifies calculations.

Rounding or rounding off means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. For example, replacing $ 23.4476 with $ 23.45, the fraction 312/937 with 1/3, or the expression √2 with 1.414. Rounding is often done to obtain a value that is easier to report and communicate than the original.
We round numbers according to the following rules: If the digit in the place smaller by one than the place to which we round is 0, 1, 2, 3 or 4, then we round the number down. Then the digit in the place to which we round does not change and smaller places are replaced by zeros. In such case we talk about under‑approximation.
