Float Typecast

Typecast a floating-point type to an unsigned integer or vice versa

• 

Libraries:
HDL Coder / HDL Floating Point Operations

Description

The block casts the underlying bits of the input to the corresponding fixed-point or floating point representation. The input and output of the block contain the same number of bits.

Input Data Type	Output Data Type
half	uint16
single	uint32
double	uint64
uint32	single
uint64	double
uint16	half

This figure shows how the block mask, behavior, and output data type changes dynamically depending on the input data type that you specify.

Ports

Input

Port_1(u) — Input signal

scalar | vector

Port to provide input to the block.

Data Types: singledouble | uint32 | fixed point

Output

Port_1(y) — Output signal

scalar | vector

Port to obtain calculated output from the block.

Data Types: single | double | uint32 | fixed point

Extended Capabilities

C/C++ Code Generation
Generate C and C++ code using Simulink® Coder™.

HDL Code Generation

Generate VHDL, Verilog and SystemVerilog code for FPGA and ASIC designs using HDL Coder™.

The block supports HDL code generation in the Native Floating Point mode. To use this mode, specify single or uint32 data types as input to the block. With the HDL Code Advisor, you can replace Data Type Conversion blocks that use the Stored Integer (SI) mode and convert between floating-point and fixed-point data types.

The block supports code generation for complex signals.
