biguintle
Encode / decode unsigned BigInt as little endian
Usage
var bigUintLE = var bigUint = 2n ** 64n - 1n // UINT64_MAX var buf = bigUintLE var num = bigUintLE
API
var buf = bigUintLE.encode(bu, [buf, [byteOffset]])
Write BigInt
bu
to optional Buffer
or TypedArray
buf
at optional
Number
byteOffset
. If buf
is not set a new Buffer
is allocated the size
of the byte width of bu
. byteOffset
defaults to 0
.
var bytes = bigUintLE.encode.bytes
Number
of bytes last encoded
var bigUint = bigUintLE.decode(buf, [byteOffset], [byteLength])
Read BigInt
from Buffer
or TypedArray
buf
at optional
Number
byteOffset
for optional Number
byteLength
bytes. Note that if you
do not give a byteLength
all of buf
will be decoded, since BigInt
s do
not have a natural width.
var bytes = bigUintLE.decode.bytes
Number
of bytes last decoded
var bytes = bigUintLE.encodingLength(bu)
Number
of bytes required to encode BigInt
bu
