How to convert binary to floating points?

I have the following code,which converts the wavdata into binary sequence.

wavbinary = dec2bin( typecast(single(wavdata(:)),'uint8'),8)-'0';

Now I want to convert the binary bits into floating poins such that the new floating points should match to the wavdata contents.

help me out!

Thank you

wavsingle = typecast(uint8(sum(wavbinary .* 2.^(7:-1:0), 2)), 'single')
