round to the nearest whole number

To round to the nearest whole number, you look at the digit in the tenths place (the first digit to the right of the decimal point):

• If the tenths digit is 0, 1, 2, 3, or 4 → round down (the whole-number part stays the same).

• If the tenths digit is 5, 6, 7, 8, or 9 → round up (add 1 to the whole-number part).

Examples:

• 2.82.82.8 → tenths digit is 8 (≥ 5) → rounds to 3.

• 26.4526.4526.45 → tenths digit is 4 (< 5) → rounds to 26.

• 73.275473.275473.2754 → tenths digit is 2 (< 5) → rounds to 73.

• 276.72185276.72185276.72185 → tenths digit is 7 (≥ 5) → rounds to 277.

For negative numbers, the same tenths-rule applies, but “rounding up” means going to the integer farther from zero (more negative):

• −3.4-3.4−3.4 → tenths digit 4 (< 5) → rounds to −3-3−3.

• −3.6-3.6−3.6 → tenths digit 6 (≥ 5) → rounds to −4-4−4.

If you’d like, I can walk through specific numbers you want to round step by step.
