Question

In need to construct System.Single values (= IEEE 754 “single precision” 32-bit floats) from their bit pattern, represented as 4 bytes (or an int32 value, big endian).

How do I do this in .NET/F#?

Answer 1

You can turn a byte array into a Single using the BitConverter class

byte[] data = new byte[4];
float f = BitConverter.ToSingle(data, 0);

to go from an into to a byte array:

int i = 1234;
byte[] data = BitConverter.GetBytes(i);

(my code is in C#, but I’m sure it is easy enough for you to convert to F#)
