I have a quantized sin wave with amplitude varying from -1 to +1 with each level of size 2^(-24),i.e., 24 bit quantiser. I need to represent the values (fractional and negative) as the binary numbers e.g, 0.004 should be represented as 0.0000001100 etc. How do I get that? Thanks in advance.

T = round(TheNumber * 2^23);
if T > 0
Q = dec2bin(T, 24) - '0';
else
Q = dec2bin(2^24 + T, 24) - '0';
end
