Is there a list somewhere that give numbers to all the controller buttons?

I noticed that these values are used to refer to the controller for instance:
B = #%00100000

those are actually upside down in nesmaker

#%00000000
Right | left | down | up | start | select | B | A

so if you want to do things with A button for example, you do

#%00000001

not #%10000000

this is the case atleast in 4.1.4, i havent updated to 4.1.5 yet so i dont know if this has been changed.

Mugi's right, it has always been inverted (don't know why) and still is.
