Question: I'm getting a Bluetooth Characteristic from a Bluetooth controller with [flutter blue](https://pub.dev/documentation/flutter_blue/latest/flutter_blue/BluetoothCharacteristic-class.html) as a List. This characteristic contains weight measurement of a Bluetooth scale. Is there a function to convert this list of ints to a Double?

I tried to find some background on float representations by reading the IEEE 754 standard. There is the dart library typed\_data but I am new to dart and have no experience with this lib.

Example: 

I have this List: [191, 100, 29, 173] which is coming from a bluetooth controller as a IEEE754 representation for a float value. 
Now i believe i have to convert each int to hex and concat these values: `bf 64 1d ad`

Next thing need to do is convert this to double, but i cannot find a function to convert hex to double. Only `int.parse("0xbf641dad")`.

Answer: 
I guess your mean to convert the list of ints to a **list** of floats, not to a single float, right?
First, dart has no type called `float`. Instead it has type `double`. To convert it, you can use the `map()` function:

```
var listInt = [1, 2, 3];
var listDouble = list.map((i) => i.toDouble()).toList();

```
If you already have: 

```dart
int.parse("0xbf641dad")

```

I don't see why this wouldn't work:

```dart
int.parse("0xbf641dad").toDouble();

```
