You do not understand how you get that number.
If you have a number of the form AB.cdefgh then how should the output be formed?

x = 40.201109;
xs = sprintf('%.6f', x);
a = str2double(xs(1:2));
b = str2double(xs(end-3:end-1));
c = str2double(xs(end-2:end));
This presumes there are exactly 6 significant decimal places. It is not generally possible to figure out how many significant decimal places a binary floating point number has -- for example 40.201109 is stored internally as 40.201109000000002424712874926626682281494140625 exactly.
