dataview.getFloat64(byteOffset [, littleEndian])
- The offset, in byte, from the start of the view where to read the data.
- Optional Indicates whether the 64-bit float is stored in
little- or big-endian format. If
undefined, a big-endian value is read.
A signed 64-bit float number.
- Thrown if the
byteOffsetis set such as it would read beyond the end of the view.
There is no alignment constraint; multi-byte values may be fetched from any offset.
