Converting a big.Int to little-endian byte slice

问题

I have a big.Int and want to convert it to a little-endian byte slice. If I use Int.Bytes, I get the big-endian byte slice.

Is there any way to get little-endian byte slice for big.Int?

回答1:

The simplest solution is to reverse the slice returned from Bytes():

b := bigInt.Bytes()
for i := 0; i < len(b)/2; i++ {
    b[i], b[len(b)-i-1] = b[len(b)-i-1], b[i]
}
