buf.readFloatLE([offset])

• offset <integer> 开始读取之前要跳过的字节数。 必须满足 0 <= offset <= buf.length - 4。 默认值: 0。
• 返回: <number>

从指定 offset 处的 buf 读取 32 位小端序浮点数。

const buf = Buffer.from([1, 2, 3, 4]);

console.log(buf.readFloatLE(0));
// 打印: 1.539989614439558e-36
console.log(buf.readFloatLE(1));
// 抛出 ERR_OUT_OF_RANGE。

• offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 4. Default: 0.
• Returns: <number>

Reads a 32-bit, little-endian float from buf at the specified offset.

const buf = Buffer.from([1, 2, 3, 4]);

console.log(buf.readFloatLE(0));
// Prints: 1.539989614439558e-36
console.log(buf.readFloatLE(1));
// Throws ERR_OUT_OF_RANGE.
