Buffer.readIntLE - buffer - Node

method Buffer.readIntLE

Usage in Deno

import { type Buffer } from "node:buffer";



Buffer.readIntLE(offset: number,
byteLength: number,
): number

Reads byteLength number of bytes from buf at the specified offset and interprets the result as a little-endian, two's complement signed value supporting up to 48 bits of accuracy.

import { Buffer } from 'node:buffer';

const buf = Buffer.from([0x12, 0x34, 0x56, 0x78, 0x90, 0xab]);

console.log(buf.readIntLE(0, 6).toString(16));
// Prints: -546f87a9cbee

Parameters



offset: number

Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - byteLength.



byteLength: number

Number of bytes to read. Must satisfy 0 < byteLength <= 6.

Return Type

number
