how can I convert negative signed floating values into binary ?

Hi. I designed ADC in simulink and now I want to convert final scalar values into binary (digital form). how can I convert these values into binary ? The values are like that : 1) -0.5 2)-30.5 3)-62.5 4)43.5 5)37.5

If i remove this fraction by doing this :

Dout=Dout+0.5; % Dout is final sampled scale value as I explained above

Dout_bin= dec2bin(typecast(int8(Dout),'uint8')); y = Dout_bin; then it shows an error how can I remove this error as well ?

Data 'y': Character outputs are not supported in Simulink and Stateflow. Cast 'y' to int8 or uint8 instead. Fix the indicated errors, or explicitly specify sizes and/or types for all block outputs.

is there any way in either script form or in simulink ? I attached my design. kindly help me in this regard.

Thanks

Subtract '0' from the output of dec2bin. Also be sure to specify width 8 for dec2bin.

Yes Sir, I found it . I was wrongly typing '0'. Thank you Sir.

can't I use Integer to bit converter block here ? I tried but it shows an error that " Error in port widths or dimensions. Output port 1 of 'ADC_ch2_DM/ADC1 ' is a matrix with a maximum size of [1x10000]

How can this error be fixed? I attach the design.

Thanks
