Why do we use rule 5 to round?
Rule 5 for rounding, often referred to as "round half to even," is used to minimize bias in rounding when numbers are equidistant from two potential rounded values. This method helps maintain statistical accuracy and prevents systematic overestimations or underestimations in large datasets. By rounding to the nearest even number, it balances out rounding errors over time, making it a preferred method in various mathematical and statistical applications.
When you round a 5 does it stay the same or change?
When rounding a number, if the digit to the right of the rounding place is exactly 5, you typically round up. However, if you're following the "round half to even" rule (also known as "bankers' rounding"), you would round to the nearest even number. For example, rounding 2.5 results in 2, while rounding 3.5 results in 4. Thus, depending on the rounding method used, a 5 can either stay the same or change.

What is the rule used for rounding decimals?
The rule that is taught in schools is that rounding is determined by the value of the next digit. If it is 4 or less you would simply remove all the digits after the point of rounding. If the digit is 5 or more, you remove all the digits after the point of rounding but also increase the final digit of the rounded number by 1. Unfortunately, this method is flawed because it introduces a systematic bias in the way 5s are rounded. 0 does not need rounding; 1, 2, 3 and 4 should be rounded down; 6, 7, 8 and 9 should be rounded up. The two main ways of rounding 5 is to ensure that the last "surviving" digit is always odd or always even. The IEEE 754 standard is to round to even.
