# interpretAsDword, interpretAsFloat, interpretAsQword, interpretAsDouble

[Valid for](../../../Shared/FeatureAvailability.md):  CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

## Function Syntax

* `dword interpretAsDword(float x);`
* `float interpretAsFloat(dword x);`
* `qword interpretAsQword(double x);`
* `double interpretAsDouble(qword x);`

## Description

These functions interpret the actual bytes of a value as if the value was of another data type.

**InterpretAsFloat** for example takes the four bytes or a dword, interprets them as if they were four bytes of an IEEE single precision floating point number, and returns that number.

**InterpretAsDouble** interprets eight bytes as if they were an IEEE double precision floating point number.

**InterpretAsDword** and **InterpretAsQword** are the inverse functions.

## Parameters

* **x**: The number which shall be interpreted.

## Return Values

The interpreted value.

## Example

```c theme={null}
// take a message with 8 bytes representing a double number
on message MessageWithDoubleSignal
{
  qword rawBytes;
  double value;
  rawBytes = this.qword(0);
  value = interpretAsDouble(rawBytes);
  write("The value is %g", value);
}
```
