Sis a coefficient that determines the precision of the fixed-point representation. This value is called theslope. Bis an additive correction called thebias. The quantized integerQis the only part of the fixed-point representation that varies in value. In the generated code, the quantitiesSandBare...
Convert Floating-Point Model to Fixed Point In this example, learn how to:Convert a floating-point system to an equivalent fixed-point representation. The Fixed-Point Tool automates the task of specifying fixed-point data types in a system. In this example, the tool collects range data for ...

Examine the results in the Contents pane of the Fixed-Point Tool. Because you ran the model in Double override mode, you get an accurate, idealized representation of the simulation minimums and maximums. These values appear in the SimMin and SimMax parameters. Now that you have an accurate...
In the first case, since the 'OverflowMode' is 'wrap', the output will be zero once the limit is exceeded (for WordLength = 8, the limit is 255). Now, consider the Fixed point representation for 0.999:
(1, 31, 3). I want to reduce this to 24 bits. The largest value is 9107852, andceil(log2(9107852)) = 24, so I need 24 bits to the left of the binary point, plus sign bit. To get that into a 24-bit signed representation, I needfixdt(1, 24, -1), hence the LSB is 2...
