Float Extract Bits block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink / Logic and Bit Operations

Description

The Float Extract Bits block accepts a signal containing floating-point data and outputs a signal containing the binary representation of the data. For more information on this binary representation, see the IEEE Standard for Floating Point Arithmetic.

Ports

Input

Port_1 — Signal containing floating-point data

scalar | vector | matrix

Signal containing floating-point data, specified as a scalar, vector, or matrix.

Data Types: single | double | half | bus

Output

Port_1 — Binary representation of data

scalar | vector | matrix

Binary representation of data, returned as a scalar, vector, or matrix. Float Extract Bits calculates the fixed point output based on the Output mode parameter.

Data Types: int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | fixed point

Parameters

Output mode — Parts of data to output

All bits (default) | Range of bits | Sign | Mantissa | Exponent

Parts of data to output as its binary representation, specified as:

• All bits

• Range of bits

• Sign

• Mantissa

• Exponent

Programmatic Use

Block Parameter: OutputMode

Type: character vector

Values: 'All bits' | 'Range of bits' | 'Sign' | 'Mantissa' | 'Exponent'

Default: 'All bits'

Bit range ([start end], 0-based relative to LSB) — Range of bits to return

[0 15] (default) | vector

Range of bits of the signal to return, specified as a vector.

Programmatic Use

Block Parameter: BitRange

Type: character vector

Values: '[0 15]' | vector

Default: '[0 15]'

Block Characteristics

Data Types	double | half | single
Direct Feedthrough	yes
Multidimensional Signals	no
Variable-Size Signals	no
Zero-Crossing Detection	no

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.
