Python float to hexadecimal & hexadecimal to float, and default flaot vs. fp32

 import struct

    return hex(struct.unpack('<I', struct.pack('<f', f))[0])

def hex_to_float(h):

    return struct.unpack('!f', bytes.fromhex(h))[0]

hex_val = "0xbf557ca4"

float_val = hex_to_float(hex_val.replace("0x", ""))

print(f"-0.8339 -> 0xbf557ca4 -> {float_val} <- -0.8339331150054932")
