Introduction to Fixed Point Number Representation

WebA fixed-point value can be represented to within half of the precision of its data type and scaling. The term resolution is sometimes used as a synonym for this definition. For example, a fixed-point representation with four bits to the right of the binary point has a precision of 2 -4 or 0.0625, which is the value of its least significant bit. WebJun 30, 2024 · Let's assume you have a signed fixed point defined with 3 digits left of the decimal point and 2 digits right of it. The smallest difference between one value and another is 0.01. The smallest values not equal to zero are -000.01 and +000.01. The largest values are -999.99 and +999.99. Rounding is presumed. ios download for macbook pro
