Rounding to a certain number of decimal places 4.737 rounded to 2 decimal places would be 4.74 (because it would be closer to 4.74). 4.735 is halfway between 4.73 and 4.74, so it is rounded up: 4.735 rounded to 2 decimal places is 4.74.

What is Rounding Off? Rounding off means a number is made simpler by keeping its value intact but closer to the next number. It is done for whole numbers, and for decimals at various places of hundreds, tens, tenths, etc. Rounding off numbers is done to preserve the significant figures.

If the decimal portion is less than 0.5, we round down, if the decimal portion is more than 0.5, we round up, and if the decimal portion is exactly 0.5, we look at the place value to the left of the five (yes, really, the left!). If it’s an odd number, you round up, and if it’s an even number, you round down.

To round this to the third decimal, note that 1 is the third number in the decimal series. The number following it is 5, and the number after the 5 is not zero. This is an indication to round up, so the 1 should become 2, making pi rounded to three decimal places 3.142.

Rounding in decimals works identically to rounding with whole numbers: if the number immediately to the right of the target is 5 or more, round up by making the target value one greater and then change the rest of the numbers to the right of the target to zero; otherwise, round down by keeping the target number the …

To round 129.257 to the nearest hundredth consider the thousandths’ value of 129.257, which is 7 and equal or more than 5. Therefore, the hundredths value of 129.257 increases by 1 to 6….129.257 Rounded to the Nearest Hundredth.

It means to give four places after the decimal point, so pi rounded to four decimal places for instance, would be 3.1416, because 3.14159265… etcetera when rounded off to four places is that.

Here’s the general rule for rounding: If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.

To round 3.9 to the nearest tenth consider the hundredths’ value of 3.9, which is 0 and equal or more than 5. Therefore, the tenths value of 3.9 increases by 1 to 0….3.9 Rounded to the Nearest Tenth.

6.5 Rounded to the Nearest Whole Number

Round up means to arrest, while round off means to conclude or end a programme: The police have rounded up the suspects.

Because everyone prefers even numbers. Rounding 5 up means that as many numbers are rounded up as are rounded down. If you consider single-digit numbers, then 0, 1, 2, 3, 4 are rounded down, and 5, 6, 7, 8 and 9 are rounded up.

Half Round Up

If the digit is 5 or greater, then you round up. The symbol ≈ means approximately the same or about equal. This is a useful symbol for when you are rounding a number.

8 Rounded to the Nearest Whole Number

We round numbers because the estimate (rounded number) is used when we can’t find an exact WHOLE number or is used to make a number continuing on forever (0.333333333333333333333333333333333333333333 etc.) a whole number.
