buf.readFloatBE([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 位大端序浮点数。

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

console.log(buf.readFloatBE(0));
// 打印: 2.387939260590663e-38

• 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, big-endian float from buf at the specified offset.

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

console.log(buf.readFloatBE(0));
// Prints: 2.387939260590663e-38
