Description

The Data Type Scaling Strip block strips the scaling off a fixed-point signal. It maps the input data type to the smallest built-in data type that has enough data bits to hold the input. The stored integer value of the input is the value of the output. The output always has nominal scaling (slope = 1.0 and bias = 0.0), so the output does not distinguish between real world value and stored integer value.

Examples

Remove Scaling from a Fixed-Point Signal

This example shows how to strip the scaling from a fixed-point input signal. To do so, the Data Type Scaling Strip block maps the input to the smallest built-in data type that has enough data bits to hold the input. The stored integer value of the input is the value of the output.

Ports

Input

Port_1 — Input signal

scalar | vector | matrix

Input signal, specified as a scalar, vector, or matrix. The block strips the scaling off a fixed-point input signal, and outputs the stored integer value with the smallest possible built-in data type.

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

Output

Port_1 — Input signal mapped to built-in data type

scalar | vector | matrix

Stored integer value of the input signal with the smallest possible built-in data type, and the same dimensions as the input.

Data Types: single | double | int8 | int16 | int32 | uint8 | uint16 | uint32
