[SR-Users] How to check a bit (1/0) of a pseudo-variable?

[Daniel-Constantin Mierla]

Hello,

that function is probably for ser-like AVPs.

back to your original need, you can use directly if conditions like:

if($var(x) & 2) { ... }

will be true if the second bit is set. You have to use the power of two 
for the appropriate integer value to match the bit position. The master 
branch has bitwise left/right shift operations as well -- I was thinking 
of backporting since they were in 1.x but lost in integration of the 
core interpreter for 3.0, reported by Juha, so it is not really a new 
feature:

Cheers,
Daniel
