buf.readInt16LE([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 读取有符号的小端序 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.readInt16LE(0));
// 打印: 1280
console.log(buf.readInt16LE(1));
// 抛出 ERR_OUT_OF_RANGE。

• 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, little-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.readInt16LE(0));
// Prints: 1280
console.log(buf.readInt16LE(1));
// Throws ERR_OUT_OF_RANGE.
