Documentation for BufferwriteDoubleLE/writeDoubleBE is confusing

[broofa]

The documentation for these methods has the following:

buf.writeDoubleBE(0xdeadbeefcafebabe, 0);

However 0xdeadbeefcafebabe a particularly poor value choice. To the naive reader, it implies this method is for writing 64-bit integers, and that JS supports 64 bit integers (which it doesn't. E.g. (0xdeadbeefcafebabe).toString(16) yields deadbeefcafeb800).

It would be clearer if the example used something like 1234.5678 or Math.PI or 1.2345e67 .
