"WebNov 22, 2016 · Biased vs. unbiased rounding. The technique of adding 0.5 and then rounding down ( round (x) = floor (x+0.5)) is fairly common, and in many PC calculations, that’s all that’s needed. For some applications this isn’t enough, because this type of rounding is biased, namely values of exactly m+0.5 m + 0.5 for integer m m will always … " - Fixed point computer arithmetic

In computing, fixed-point is a method of representing fractional (non-integer) numbers by storing a fixed number of digits of their fractional part. Dollar amounts, for example, are often stored with exactly two fractional digits, representing the cents (1/100 of dollar). More generally, the term may refer to … See more A fixed-point representation of a fractional number is essentially an integer that is to be implicitly multiplied by a fixed scaling factor.
