WebFor example, the specification Q3.12 describes a signed binary fixed-point number with a w = 16 bits in total, comprising the sign bit, three bits for the integer part, and 12 bits that are the fraction. That is, a 16-bit signed (two's complement) integer, that is implicitly multiplied by the scaling factor 2 −12 WebApr 27, 2013 · For base 2 it is called a "binary point". The term that is generic for any base is "radix point". In a number such as 5.43, the radix point is "fixed" in that the weight of a given digit is determined by how far it is to the left of the right. Normally, the weight of the digit immediately to the left of the radix point is 1. camping de bert allier
