Convert four 8 bit values to floating point

Question

See more:

Have a device that when polled returns answer as four 8 bit bytes that together (32 bits) represent a single precision floating point number.
How can I easily convert the four 8 bit bytes to a float?

What I have tried:

Have a routine that examines the four 8 bit bytes bit by bit, does the crazy math to convert it to a single precision float. Computations get crazy. Seems there must be an easier way.

if your whatever .NET flavor doesn't provide the BitConverter library, see:

c# - How do I convert an array of floats to a byte[] and back? - Stack Overflow[^]

You can use the BitConverter.ToSingle Method (Byte[], Int32) (System)[^].
