Is it possible to read the bit of an OPC Tag set as an integer?

I want to read an individual bit off a DINT tag pulled from a PLC in scripting, without having to break the tags into individual Igniton tags.

There 's an expression function [getBit](https://docs.inductiveautomation.com/display/DOC79/getBit)…  
If you want in scripting, look [here](https://wiki.python.org/moin/BitManipulation)…

```auto
def getbit(x,n):
  "Get the n-th bit of the number x"
  return x & (1 << n) and 1 or 0

```

Explanation: x & (1 \<\< n) means bitwise AND between x and 2^n. And the expression P and 1 or 0 means: if P then return 1, otherwise return 0.

And this works for numbers of any size. Python is not limiting you to 32 bit integers.
