buf.readInt16BE([offset])
从指定的 offset
处的 buf
读取有符号的大端序 16 位整数。
从 Buffer
读取的整数被解释为二进制补码有符号值。
import { Buffer } from 'node:buffer';
const buf = Buffer.from([0, 5]);
console.log(buf.readInt16BE(0));
// 打印: 5
const { Buffer } = require('node:buffer');
const buf = Buffer.from([0, 5]);
console.log(buf.readInt16BE(0));
// 打印: 5
offset
<integer> Number of bytes to skip before starting to read. Must satisfy0 <= offset <= buf.length - 2
. Default:0
.- Returns: <integer>
Reads a signed, big-endian 16-bit integer from buf
at the specified offset
.
Integers read from a Buffer
are interpreted as two's complement signed values.
import { Buffer } from 'node:buffer';
const buf = Buffer.from([0, 5]);
console.log(buf.readInt16BE(0));
// Prints: 5
const { Buffer } = require('node:buffer');
const buf = Buffer.from([0, 5]);
console.log(buf.readInt16BE(0));
// Prints: 5
