function [bits]=calcbits(bounds,precision)
% function [bits]=calcbits(bounds,precision)
% Determine the number of bits to represent a float number to the precision
% provided.
%
% bits      - the number of bits required per variable
% bounds    - the bounds on the variables
% precision - the least difference to distinguish two numbers
bits=ceil(log2((bounds(:,2)-bounds(:,1))' ./ precision));
% bits=ceil(log( (bounds(:,2)-bounds(:,1))' .* 10.^precision+1) ./ log(2));
