Hi, I want to convert decimals between 0 and 1 into binary form which can be represented exactly up to 11 binary digits say, so 1/2^11, 2/2^11, 3/2^11......to 2^11-1/2^11 only, is there a good code or build in function for this?
Also, is there a function which can return the no of 1's or 0's in the binary form of a particular value above?
Thanks
Joe

B = dec2bin( round(X * 2^11), 11 ) - '0';
nnz(B)
sum(B)
length(B) - nnz(B)
