![]() ![]() If the digit to the immediate right is 4 or below then the place value to the left will remain the same and all other digits to the right of the place value rounded will become 0’s. The digit in the place value to the immediate right of the place value being rounded determines the rounded value. Understand that when rounding to any place value, the number to the immediate right is the determining place value and any additional place values to the right are not considered in the rounding process. ![]() In the base 10 system, the value of each place is 10 times the value of the place to the immediate right. Scroll down for a preview of this learning objective’s games and the concepts. This learning objective directly references 4.NBT.A.3 as written in the common core national math standards. The Round Whole Numbers To Any Place l earning objective - based on CCSS and state standards - delivers improved student engagement and academic performance in your classroom, as demonstrated by research. If number is not numeric, ROUND returns a #VALUE! error.In this series of games, your students will learn to use place value understanding to round multi-digit whole numbers to any place.If number is already rounded to the given number of places, no rounding occurs.The ROUND function rounds to a specified level of precision, determined by num_digits.To truncate decimal places, use the TRUNC function.To round down and return an integer only, use the INT function.To round up to the nearest specified multiple, use the CEILING function.To round up to the nearest specified place, use the ROUNDUP function.To round down to the nearest specified multiple, use the FLOOR function.To round down to the nearest specified place, use the ROUNDDOWN function.To round to the nearest multiple, use the MROUND function.To round with standard rules, use the ROUND function.Other rounding functionsĮxcel provides a number of rounding functions, each with a different behavior: For example, to round down the result of A1 divided by B1, you can ROUND in a formula like this: =ROUND(A1/B1,0) // round result to nearest integerĪny formula that returns a numeric result can be nested inside the ROUND function. Other operations and functions can be nested inside the ROUND function. To round down values to the left of the decimal point, use zero or a negative number for digits: =ROUND(A1,0) // Round to nearest whole number =ROUND(A1,4) // Round to 4 decimal places ![]() =ROUND(A1,3) // Round to 3 decimal places =ROUND(A1,2) // Round to 2 decimal places To round values to the right of the decimal point, use a positive number for digits: =ROUND(A1,1) // Round to 1 decimal place This behavior is summarized in the table below: Digits Use zero (0) for num_digits to round to the nearest integer. When num_digits is less or equal to zero, the ROUND function rounds on the left side of the decimal point. When num_digits is greater than zero, the ROUND function rounds on the right side of the decimal point. Number is the number to be rounded, and num_digits is the place at which number should be rounded. ROUND takes two arguments, number and num_digits. The ROUND function rounds a number to a given number of places. ROUND rounds up when the last significant digit is 5 or greater, and rounds down when the last significant digit is less than 5. ![]()
