Convert decimal to IEEE 754 32 bit single precision floating point

I have the following decimal values. 190, 51, 39, 116. How can i convert this to IEEE 754 32 bit single precision floating point to get the value of -0.174955189228058. I need to use this as a matlab function block in Simulink, therefore i cannot use the conversion of hexadecimal to IEEE 754 32 bit single precision floating point matlab script.

function y = fcn(~)
%#codegen

t0 = zeros(1, 4, 'uint8');
t0 = uint8([190, 51, 39, 116]);
t0 = fliplr(t0);
y = zeros(1, 1, 'single');
y = typecast(t0,'single');

I used a ground as the input and sent the output to a display block, and it seems to work fine. Probably it could be simplified a little. I suspect, though, that you would be wanting to use the input signal, and I do not know what datatype your input signal would be.

The data type of my input is uint8 and your function works perfectly. Thanks a lot for your help.
