R2026b

Namespace: target

Describe floating point data type implemented by compiler for target hardware

expand all in page

Description

Use a target.FloatingPointDataType object to describe a floating point data type that is implemented by the target hardware compiler but is not specified by a C language standard.

To create a target.FloatingPointDataType object, use the target.create function.

The target.FloatingPointDataType class is a handle class.

Describe the suffix appended to numeric literal in C or C++ code, which indicates data type. For example, some ARM® compilers support the use of the literal suffix f16 for the _Float16 data type, which allows the specification of literals of the data type in C or C++ code, say, 1.23f16.
