This browser-based application rounds one or more integers and returns their approximated values in the output. You can adjust the rounding precision in the options and round integers to ones, tens, hundreds, thousands, or any other place value. You can also switch between rounding methods and round integers up, down, to the nearest integer, or to the nearest half. Created by math nerds from team Browserling.
With this quick webapp, you can round off integers to ones, tens, hundreds, thousands, and more place values. Rounding an integer makes it simpler to interpret and work with as the less significant digits (on the right side) are turned into zeros. For example, you can round the integer 521 to tens and get 520, or round the value 2590 to hundreds and get 2600. These two examples use a rounding method that is called "Round to the Nearest Integer". As you can see in the first case after rounding, the digit 2 (in tens position) remained as it was but the digit 1 (in unit position) got dropped and converted to 0. In the second integer, the digit 5 (in hundreds position) was turned into the digit 6 and digits in tens and ones positions got dropped. The rounding in these examples followed this rule – if the dropping digit is in the range from 0 to 4, then the more significant digit (to the left) remains unchanged. If the discarded digit is between 5 and 9, then the more significant digit is increased by 1. You can also switch to the "Round Up (Ceil)" mode or "Round Down (Floor)" in the options and always round an integer to the nearest higher or lower value. For example, rounding 521 up to tens will produce 530 but rounding the same integer 521 down to tens will produce 520. The last rounding method is "Round to a Half". It's very similar to rounding to the nearest integer but here the nearest integer also includes any integer ending in 5. If the dropping digit is 0, 1, or 2, then the action is to round the integer down. If the dropping digit is 8, or 9, then the action is to round the integer up. If the dropping digit is 3, 4, 5, 6, or 7, then the action is to change the dropping digit to 5. For example, the integer 122 will be half-rounded to 120, the integer 123 will be half-rounded to 125, and the integer 128 will be half-rounded to 130. After choosing the rounding mode, you can specify the integer precision. You can round your integers to ones, tens, hundreds, thousands, or other precision. The utility also supports custom rounding precision. You can select the custom precision mode and enter the accuracy as a power of ten. For example, 10000 (round to ten thousands), 1000000000 (round to billions). As an extra feature, you can also round integers with a decimal part. For example, if you enter 0.001 in the custom precision, then the input value will be rounded to 3 decimal places. Integerabulous!
This example loads a list of integers from 100 to 110 as the input data and rounds them to tens. It uses the rounding method that rounds them to the nearest integer. This means that if the last digit is from 0 to 4, then they are rounded down, and if the last digit is from 5 to 9, then they are rounded up. In the output, we get only two different integers 100 and 110, which are approximate values of input integers with an accuracy of ten.
In this example, we use a rounding algorithm that gets rid of the coin part in different currencies. As currencies have the integer part and the fractional part, we choose the round-to-one rounding method. As a result, the program discards the decimal part of each money amount, leaving only the integer part of the amount. In the rounding up method, the presence of at least one coin in the amount bumps up the banknote value by one.
In this example, we're working with data that shows the names of all oceans and their physical area in square kilometers. The area has the precision of up to one thousand km but we'd like to work with simpler numbers and have a precision of ten million. With this tool, we can easily do it and round the integer areas in the data in-place without even having to extract them. We select the round down method and switch to custom precision mode. We enter the value 10000000 in the place value options, which means rounding with an accuracy of ten million.
