WebIn the Fixed-Point Blockset, you specify radix point-only scaling with the syntax 2^-E where E is unrestricted. This creates a MATLAB structure with a bias B = 0 and a fractional slope F = 1.0. For example, the syntax 2^-10 defines a scaling such that the radix point is at a location 10 places to the left of the least significant bit. WebWith the Fixed-Point Designer™ software, you can select a fixed-point data type whose scaling is defined by its binary point, or you can select an arbitrary linear scaling that suits your needs.
