buf.readIntLE(offset, byteLength)

• offset <integer> 开始读取之前要跳过的字节数。必须满足 0 <= offset <= buf.length - byteLength。

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

• byteLength <integer> 要读取的字节数。必须满足 0 < byteLength <= 6。

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

• 返回:<integer>

  \Returns: <integer>

从指定的 offset 处的 buf 读取 byteLength 个字节,并将结果解释为支持最高 48 位精度的小端序、二进制补码有符号值。

\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: -546f87a9cbeeconst { Buffer } = require('node:buffer');
