What is the Nearest Integer?

The nearest integer of a decimal number is the value of that number once it has been rounded to the nearest counting number (a number without decimals or fractional parts, such as -1,0,1,2, …) depending on the value of the first digit (the tenths place located to the right of the decimal separator).

How to Round to the Nearest Integer?

To round a decimal number to the nearest integer examine the value of its first decimal digit. If the value is equal to 5 or greater, increase the value in the integers ones place by 1 and eliminate all digits. If the value is equal to 4 or less, simply remove all the digits and the decimal separator.

For example:

• 1.36: The first digit’s value is 3, so we round down: 1.36 → 1
• 15.8: The first decimal value is 8, so we round up: 15.8 → 16
• 11 Nothing to be done, the tenths’ value is 0.

Round Up to the Nearest Integer

If the digit at the first decimal place of a certain number is >= 5, then, as stated by the general rounding rules, you round up to the nearest integer. However, the term round up to the nearest integer means that all first decimal place values in between 1 and 9 are rounded up by adding 1 to the value in the integer ones place, and then deleting the decimal point and all digits.

Round Down to the Nearest Integer

If the digit at the first decimal place is < 5, then, as stated by the general rounding rules, you round down to the nearest integer. However, the term round down to the nearest integer means that first decimal place in between 1 and 9 are rounded down by deleting the decimal point and all digits.

Bottom Line

Each and every resulting (rounded) number has always the same value as the input number, but its value is less exact.
