Need help for a code that changes numbers into binary normal representation and storage in a single precision. Not MATLAB built-in converter. Thanks

Of course if it is -ve integer, then the code considers it as a +ve integer but for me I know that my input is -ve and I considers it as -ve. For example if my input is
24
Then the out put is
'11000'
In the same way for -24 is also
'11000'
Since the input is -ve value it is clear that you must add -ve to get the correct result. I haven't got a result for fractions.

I suppose I need to post num2bin sometime. Too many round-tuits.

Where N is an integer:
>> N = -24;
>> V = pow2(1+fix(log2(abs(N))):-1:0);
>> Z = fix(mod(abs(N),V(1:end-1))./V(2:end)) % numeric vector
Z =
1 1 0 0 0
>> char(Z+'0') % char vector
ans = 11000
