how to remove difference error of .1e^-16

I am working on a program where I am concatenating a number(say 0.3654) after converting it to binary with other bits and then retrieving the same number later on ... when I compare these two numbers it gives an error difference of .111e^-15 which is although very less but it is affecting the results. All the numbers I m dealing with are decimal numbers (0.54354, 0.44362 applying ceil,floor, round is not working.)...can anyone please help to remove the error.

"I am concatenating a number(say 0.3654).."
Most likely you aren't. You are probably concatenating the closest binary equivalent to the decimal value 0.3654. This is not a bug in MATLAB, this is simply a side-effect of how floating point numbers are stored in binary:
etc., etc.
"can anyone please help to remove the error."
You need to design your algorithm to take floating-point error into account.
