Hey,


since all numbers are bits, for example a int is 32 bits, can't we use a 
math function to convert from bigger numbers to small numbers?

for example

     int a= 0xaabbccdd


f(a) = 0xff


we could only store 0xff

and for obtaining the a again, just use the inverse function...the 
function has to be bijective though

f-a(0xff) = 0xaabbccdd


thanks


later
