Floating-Point Specification in Simulink

Create and use floating-point data types such as single and half

Because single precision numbers use only 32 bits, they require less memory than double-precision numbers while still offering many of the benefits of floating point arithmetic. The half-precision data type occupies only 16 bits of memory, but its floating-point representation enables it to handle wider dynamic ranges than integer or fixed-point data types of the same size.

Classes

`Simulink.NumericType`	Specify floating-point, integer, or fixed-point data type
`target.FloatingPointDataType`	Describe floating point data type implemented by compiler for target hardware (Since R2021b)

Functions

`ssGetDataTypeIsDoubleSingleorHalf`	Determine whether registered data type is double, single, or half-precision data type (Since R2020b)
`ssGetDataTypeIsHalfPrecision`	Determine whether registered data type is half-precision data type (Since R2020b)
`ssRegisterDataTypeHalfPrecision`	Register half-precision data type and return its data type ID (Since R2020b)
`target.add`	Add target object to internal database
`target.create`	Create target object
`target.get`	Retrieve target objects from internal database
`target.remove`	Remove target object from internal database

Namespaces

target Manage target hardware and build tool information
