I am writing a script in the “Client Event Scripts” section would like the ability to get a single bit from an integer tag; the same result if I was to use the _**getBit()**_ function in an expression. _**getBit(**)_ does not seem to work. Has anyone run into this before and have a suggestion for an alternative?

**_getBit()_** documentation: [https://docs.inductiveautomation.com/display/DOC79/getBit](https://docs.inductiveautomation.com/display/DOC79/getBit)

No expression functions can be use in python. Use python operators. Something like:

```auto
myBit13 = bool(system.tag.read('path/to.myInteger').value & 0x2000)

```

Thanks! I have been playing around with this but have been unable to figure it out.

Lets say **Value = 8** ; in binary that’s: **1000**. Using the **getBit()** function this is what is returned.

bit1 =\> getBit(Value, 0) = 0  
bit2 =\> getBit(Value, 1) = 0  
bit3 =\> getBit(Value, 2) = 0  
bit4 =\> getBit(Value, 3) = 1

How can I return the same thing using the python **bool()** function?

Maybe just define your own `getBit` function? It’s just bit shifting:

```python
def getBit(i, n):
	return (i >> n) & 1

```

Thanks, this does exactly what I was looking for.
