buf.readInt16BE([offset])

• offset <integer> 开始读取之前要跳过的字节数。 必须满足 0 <= offset <= buf.length - 2。 默认值: 0。
• 返回: <integer>

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。

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 satisfy 0 <= 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.

const buf = Buffer.from([0, 5]);

console.log(buf.readInt16BE(0));
// Prints: 5
