Data Type Conversion and Casting

Conversion from one data type to another

Data type conversion and casting refers to changing from one data type to another. Fixed-Point Designer™ lets you create and optimize data types that meet numerical accuracy requirements and target hardware constraints.

Topics

Parameter and Signal Conversions

Conversions of data types of parameters and signals in Simulink® simulations.

Conversions and Arithmetic Operations

Example highlighting how the data types are converted and arithmetic operations are performed on inputs and parameters in the Simulink software.

Fixed-Point Arithmetic

Addition, subtraction, multiplication, casts, modulo, and two’s complement arithmetic.

Cast from Doubles to Fixed Point

Example based on the fxpdemo_dbl2fix model, which highlights many of the key features of the Fixed-Point Designer software.

Display Port Data Types

Three parts of the port display for fixed-point signals: the data type, the number of bits, and the scaling.

fi Objects and C Integer Data Types

Comparison of ANSI C integer data type ranges, conversions, and exception handling with those of fi objects.

Cast fi Objects

Information on casting fi objects.
