Supported Data Types

The Fixed-Point Designer™ software supports the following integer and fixed-point data types for simulation and code generation:

  • Unsigned data types from 1 bit to 65,535 bits

  • Signed data types from 2 bits to 65,535 bits

  • Boolean, double, single, and half

  • Scaled doubles

The fi object in MATLAB® has a word length limit of 65,535 bits.

The software supports all scaling choices including pure integer, binary point, and slope bias. For slope bias scaling, it does not support complex fixed-point types that have non-zero bias or non-trivial slope.

The save data type support extends to signals, parameters, and states.
