Via the serial inteface I get a string with hexadecimal values of a sensor.

Now I’m having trouble converting the String to a float which shall be used for further calculations.

For testing purposes this calculation is a division by 100 which should result in an integer with some decimals.

target item:

```
Number nSensorVal "val= [%.2f]"
```

rule:

```
var Number nIntVal
var Number nFloatVal
nIntVal = Integer::parseInt(sHexString, 16) // this works!
nFloatVal = ??? / 100 // no idea what to put here
nSensorVal.postUpdate(nFloatVal)
```

In place of *???* I’ve unsucessfully tried using things like

*nFloatVal = Float::parseFloat(nIntVal.state)*

or

*nFloatVal = (nIntVal.state as DecimalType) / 100*

I get a lot of errors like

*The name ‘XFeatureCallImplCustom.state’ cannot be resolved to an item or type.*

which to my knowledge indicates a type mismatch.

So how is an integer value converted to float to preserve decimal places when doing calculations?

Maybe that’s even possible in a single step?
