let obj = serializeMsgPack([100, 100, "ok", serializeMsgPack([[100, 1000.01]])]
let obj2 = deserializeMsgPack(obj)
console.log(deserializeMsgPack(obj2[3])[0][1]);// print:5.262076770253218e+228

I can't follow your code and it contains syntax errors. Here's a cleaned up version of it:

let obj1 = [[100, 1000.01]];
let msg1 = serializeMsgPack(obj1);
let obj2 = [100, 100, "ok", msg1];
let msg2 = serializeMsgPack(obj2);

let obj2_ = deserializeMsgPack(msg2);
let msg1_ = obj2[3];
let obj1_ = deserializeMsgPack(msg1_);

console.log(obj1_[0][1]); // 5.262076770253218e+228

Can you please verify the correctness of my version and that it still produces the wrong result for you? Because this code works as expected for me in Firefox 64 on Windows 10.

If the error remains for you, please specify what environment you used.

            console.log("r");
	let obj1 = [[100, 1000.01]];
	let msg1 = serializeMsgPack(obj1);
	let obj2 = [100, 100, "ok", msg1];
	let msg2 = serializeMsgPack(obj2);

	let obj2_ = deserializeMsgPack(msg2);
	let msg1_ = obj2_[3];
	let obj1_ = deserializeMsgPack(msg1_);

	console.log(obj1_[0][1]); // 5.262076770253218e+228

log:
r

Sorry, I can't reproduce this. The closest environment I have is Chrome 72.0.3626.109 (64 bit) on Windows 10. For me, the log prints the expected "1000.01", as it does in Firefox. So I'd suggest you report the bug in Chrome for Mac.
