Converting a float to bytearray

Question

So, what I am trying to do is convert a float to a bytearray but I keep on receiving both no input, and EXTREME slowing/freezing of my computer. My code is

Answer 1

It depends what you want, and what you are going to do with it. If all you want is a bytearray then:

import struct

value = 5.1

ba = bytearray(struct.pack("f", value))  

Where ba is a bytearray. However, if you wish to display the hex values (which I suspect), then:

print([ "0x%02x" % b for b in ba ])

EDIT:

This gives (for value 5.1):

['0x33', '0x33', '0xa3', '0x40']

However, CPython uses the C type double to store even small floats (there are good reasons for that), so:

value = 5.1
ba = bytearray(struct.pack("d", value))   
print([ "0x%02x" % b for b in ba ])

Gives:

['0x66', '0x66', '0x66', '0x66', '0x66', '0x66', '0x14', '0x40']
