converting switch states to decimal number

Archiver

I need my Stamp 2SX to convert the states of its two dipswitches to a
number from 0-3 using binary math, i.e.:

switch 1 off, switch 2 off => 0
switch 1 on, switch 2 off => 1
switch 1 off, switch 2 on => 2
switch 1 on, switch 2 on => 3

Is there a way to use the values of their input pins (in1 and in2) to
make this conversion using a single statement instead of a bunch of
if...then's?

Thanks

Yes, you can do it in one line of code:

switches = InA & %0110 >> 1

Do I win a prize?
