The term "arithmetic rounding" is another name for the Round-Half-Up algorithm (of which there can be both symmetric and asymmetric versions). c) WebThe round half down tie-breaking rule is not symmetric, as the fractions that are exactly 0.5 always get rounded down. This asymmetry introduces a negative bias in the roundoff errors. ...

Another way of doing this is "symmetric arithmetic", where the 5's are always rounded "away from zero" (so -2.5 rounds to -3). WebJun 22, 2006 · In many ways, this is the most intuitive of the various rounding algorithms, because values such as 5.1, 5.2, 5.3, and 5.4 will round down to 5, while values of 5.6, 5.7, 5.8, and 5.9 will round up to 6: But what should we do in the case of a “half-way” value such as 5.5.

WebFinally just a trivia; the range for negative numbers is one extra deep, e.g. 8 bits have the range -128 ~ +127. Symmetric saturation is commonly used to avoid dc bias by forcing values to swing across -127 ~ +127 Truncation is nowadays more involved and includes non rounding or dc biased rounding or dc unbiassed rounding. WebDec 25, 2010 · The difference between MROUND and CEILING and FLOOR is that MROUND rounds up or down using symmetric arithmetic rounding. For example, if the number is 77 and the multiple is 5, then MROUND gives a result of 75. However, if the multiple is changed to 7, then MROUND's result becomes 77. Once you tease the various rounding functions …

WebSep 10, 2024 · This leads us to the “round-half-even” algorithm, in which halfway values are rounded toward the nearest even number, so 5.5 will round up to 6, while 6.5 will round down to 6. This is often referred to as “banker’s rounding,” because it is commonly used in financial calculations.
