To String - Convert input signal to string signal - Simulink (original) (raw)

Convert input signal to string signal

Libraries:
Simulink / String

Description

The To String block creates a string signal from an input signal. For example, consider using this signal to convert a logical value 1 or0 to its string equivalent "false" or"true".

The To String block generates efficient code for enumerations by generating a shared function for each enumeration type. For more information on enumerations, see Simulink Enumerations.

When a MinGW® compiler compiles code generated from the block, running the compiled code may produce nonstandard results for floating-point inputs. For example, a numeric input of 501.987 returns the string "5.019870e+002" instead of the expected string "5.019870e+02".

Input

Input signal, specified as a scalar.

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

Output

expand all

Output string, specified as a scalar. This block returns the output as a string, surrounded by double quotes.

• If the input is a Boolean, the output is a logical value (1 or 0) and the block returns its textual equivalent (true orfalse).

• If the input is a numeric data type, such as an integer, single, double, or fixed point, the block returns the number as a string. For example, an input of 1 converts to "1" and an input of 0 converts to "0".
  Note
  The output string might not contain all the digits of the numeric value from the input port.

The To String block now generates more efficient code for enumerations by generating a shared function for each enumeration type. Prior to R2024b, this block generated inlined code for enumerations.
