How to get a float number of two bytes? There are two bytes. Suppose 0x02 is the lowest part and 0x04 is the highest part. How do I get a float number?

    What should be the resulting number? - Yaant
  • bytes must be cast in one way or another into an array of bytes. Then, using BitConvert. - Garrus_En

    @Garrus_En So the author does not need an int, but a float. - Yaant
  • The length of the float type is four bytes, not two. Something you do not agree. - Alexander Petrov
  • I agree with the previous answer, read the specification on float ru.wikipedia.org/wiki/… . Here, perhaps two bytes are always zero, then you can use unmanaged code - Alexsandr Ter

Suppose your number is represented like this:

float f = 2.7f; // Приводим float к массиву байт byte[] arr = BitConverter.GetBytes(f); // И обратный процесс float i = BitConverter.ToSingle(arr,0);

Hope to help understand.

  • float i = BitConvert.ToSingle (arr, 0); - Dmitry Chistik
  • I will correct in the answer, thanks. Although Int16 is the same 2 bytes in size - Garrus_En
  • only they are stored in a different memory ... - Dmitry Chistik
  • And how to correctly convert? Is the order itself important when converting? - Victor Sayapov
  • not clear comment, what do you mean? What does it mean to convert correctly? I gave an example of converting from float to byte and back. - Garrus_En
