I converted a data [0.104895105] from double to binary[0001]. But this binary data is in char form as in excel it shows like '0001'.
1. Is it possible to convert back to double data type without loosing any thing?
2. is it possible to remove ' ' from the data? Thanks in Advance.

Suppose I have a function that converts the value -2 to the value 4. I do not tell you what the function is. I ask you to convert the value 4 back to -2 without seeing my function. Can you do it?
Answer: No. There are an infinite number (Aleph 1) of functions that happen to map -2 to 4. One of them is f(x) = x^2. But that function also maps +2 to 4, so given only the value 4 there is no way to invert that function to get -2 unambiguously.

Subtract '0' from the array. That is '0' not 0

You want a numeric data type holding 4 distinguishable locations. In MATLAB, all numeric data types are displayed with whitespace between locations by any of the routines that do automatic formatting.
As far as I understand, Excel has no way of holding multiple numeric values in a single cell.
