if I byte array:
byte_array := []byte("klm,\x15\xf1
")
I would like to the byte \x15 and \xf1 to uint16 in LittleEndian order. What is the easiest way of doing it?
Tried the following:
var new_uint uint16
bff := bytes.newRead(byte_array[4:5])
err = binary.Read(buff, binary.LittleEndian, &new_uint)
but I keep getting nothing, and this is relatively complicated, is there an easier way of doing it?
Thanks...
You have 2 options, using binary.LittleEndian like you already did, a shorter way is:
u16 := binary.LittleEndian.Uint16(byte_array[4:])
Or if you like to live dangerously, you can use unsafe:
// This will return the wrong number on a BE system,
// also unsafe is not available on GAE.
u16 := *(*uint16)(unsafe.Pointer(&byte_array[4]))
