Turn random bytes to .NET decimal 0..1 fractional range

I'm playing with a TRNG usb device, and successfully turning the random bytes into various usable data in C#.

I'd like to create a .NET decimal value between 0..1 (ex: 0.37327) directly from the bytes using binary reader (or other direct bytes -> decimal) method.

// assume: byte[] random_data of appropriate length, patterned for a 0..1 range decimal value = new BinaryReader(new MemoryStream(random_data)).ReadDecimal();

I was looking for the byte format of decimal, but it looks like it may not be a standard?

• How do I convert byte values into decimals?
• .NET decimal cross-platform standard

This is for hobby work, so it's acceptable to me to use something that might change in future. I've looked at the bytes generated for sample input decimal values - I see negative and precision flags (1Ch max in last int32?), but the min/max data values dumping compiler constants are stumping me a bit, and I'm generate above zero values or invalid values:

• fractional value nearest 1 (.99...9): FFFFFF0F 6102253E 5ECE4F20 00001C00
• fractional value nearest 0 (.00...1): 01000000 00000000 00000000 00001C00

Can you help me onto the correct path for generating a full fractional 0..1 range?
