Rounded Numbers
Online calculator for rounding numbers to whole, tens, hundreds, thousands. Round a fractional number.
The very first thing to know is that any number can be rounded. Regardless of whether the number is whole or fractional, the rule is the same.
If a number needs to be rounded, it means its value will be reduced to hundredths, tenths or thousandths, and the remaining values will be discarded.
When rounding, the number that is discarded plays the main role. If it is from 0 to 5, the rounded number remains unchanged. When the number is from 5 to 9, the rounded number increases by 1.
Example:
Need to round the number 35.948 to hundredths.
This means that the digit 8 will be discarded. The previous digit, which is 4 in this case, will be increased by 1.
We have: 35.948 = 35,95
Example:
Need to round the number 0.738 to tenths.
This means that the last two digits need to be discarded – 38, pay attention to the next one after the one that remains – this is 3. In this case, it is less than 5, so no changes are made.
If the digit that is discarded is equal to 5, then 1 is added to the remaining digit.
When it is necessary to round, for example, the number 0.795 to hundredths, 5 is discarded, which means 1 is added to the previous digit. Since it is 9, it becomes 10, so 7 turns into 8: 0.795 = 0,80.
