WebNov 23, 2024 · The term "Fixed-Point" refers to the position of the binary point. The binary point is analogous to the decimal point of a base-ten number, but since this is binary rather than decimal, a different term is used. In binary, bits can be either 0 or 1 and there is no separate symbol to designate where the binary point lies. WebFor example, while a fixed-point representation that allocates 8 decimal digits and 2 decimal places can represent the numbers 123456.78, 8765.43, 123.00, and so on, a floating-point representation with 8 decimal digits could also represent 1.2345678, 1234567.8, 0.000012345678, 12345678000000000, and so on. ...

WebSep 14, 2016 · The simplest method is just to convert the whole value to an integer (ignoring the fixed point, initially), then scale the result. So for your example where you have a 6.2 fixed point number: 110010 10: Convert as integer: 11001010 = -54 Divide by scale factor = 2^2:-54 / 4 = -13.5 Note that the fractional part is always unsigned. WebDec 15, 2024 · To perform fixed-point multiplication, we can first ignore the binary point of the multiplier and multiplicand, perform the multiplication treating the operands as two’s complement numbers, and, then, determine the position of the binary point for the result.

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 representing fractional values as integer multiples of some fixed small unit, e.g. a fractional amount of hours as an integer multiple of ten-minute intervals.
