How to round decimals ? | Rounding Numbers Guide Teenage girl helping classmate with mathematics and explaining him how to solve equations When dealing with decimal numbers, rounding is an important concept that everyone should master. Rounding is useful in different situations: rounding to pay bills or in an academic setting to find out the estimate of the average score of students in a class.

  • Rounding decimals consists of rounding a decimal number to a certain number of decimal places, to save time and help us express really long numbers in shorter terms.
  • We can round decimals to the nearest wholes, tenths or hundredths, when having exact values isn’t important.
  • A rounded number has almost the same value as the original number but it is a bit less exact.

There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up.

What is 2.5 rounded to two decimal places?

Rounding modes – Depending on the situation, you will want this rounding algorithm to behave appropriately. Sometimes you want to round everything up ( 2.1 would be rounded to 3 ). Sometimes you want exact halves to be rounded up in half of the cases and down in the other half, in order to for a higher chance of an average staying close to the truth.

up – rounds away from zero.3.2 and 3.6 become 4, but -3.2 and -3.6 become -4, down – rounds towards zero. The above numbers become 3 and -3 respectively. ceil – rounds towards the larger number. It differs from rounding up by the way it handles negative numbers. Both -3.2 and -3.6 become -3, floor – it rounds towards the smaller number. Similarly, negative numbers go the opposite way than in the case of rounding down. -3.2 becomes -4, This principle is what our modulo calculator is based on. half up (default) – rounds towards the nearest neighbor. If equidistant, it rounds away from zero (just like in the up mode). For example, 3.5 becomes 4 and -3.5 becomes -4, This is how rounding is usually performed. half down – similarly to half up, it rounds to the nearest neighbor, unless it’s equidistant – then it rounds towards zero (just like in the down mode). The above numbers become 3 and -3 respectively. half even – an interesting one. Rounds towards the nearest neighbor, but if equidistant, it rounds towards the even number. Both 1.5 and 2.5 are rounded to 2,3.5 and 4.5 are rounded to 4, It prevents cumulative rounding errors and this is why it’s often used in science (we use it as a default mode in our significant figures calculator, If you’d round up all the time, the average is too high. this is why we round up half the time. The same rule (for the same reason) is used in accounting. When you want to round to the nearest cent, just use the half even mode. half ceil – the nearest neighbor, equidistant values go towards the larger number. half floor – the nearest neighbor, equidistant towards the smaller number.

What is 3.14 rounded to the nearest hundredth?

Thus, for 3.14, the number in the hundredth place is 4. To round it, we will look at the third digit after the decimal, which is 0. We know any number lower than 5 is rounded down to zero, so we will round down and the rounded number will be 3.14. Conclusion: 3.14 rounded to the nearest hundredth is 3.14 itself.
