Created page with "<h2>bShr(int, int2) : Binary shift right</h2> <pre> -- 1 >> 1 print( bShr(1,1) ) -- 0 0001 ----- 0000 </pre>"

New page

<pre>
-- 1 >> 1
print( bShr(1,1) ) -- 0

+{{CodeBox|'''function''' bShr(''int1'', ''int2'') ''':''' Integer}}
 Performs a bitwise right shift operation. This function shifts the bits of the first integer (''int1'') to the right by the number of positions specified in ''int2''. It behaves the same as Lua’s right-shift operator (<code>></code>) in Cheat Engine.
