Hi all,

Problem is I need to do do something as a multipple of the bits set on an integer, the integer is a bit array to store statii.

I need to figure out how many bits are set on an integer.

I know I can loop / iterate through the number and bittest / divide by 2 etc.

for now there are not to much so I can do with an ICASE, but I like it generic :)

Any ideas for a fast solution? Something mathematical?
