DataView.prototype.getFloat64()

The getFloat64() method gets a signed 64-bit float (double) at the specified byte offset from the start of the DataView.

Syntax

getFloat64(byteOffset)
getFloat64(byteOffset, littleEndian)

byteOffset: The offset, in byte, from the start of the view where to read the data.
littleEndian: Optional Indicates whether the 64-bit float is stored in little- or big-endian format. If false or undefined, a big-endian value is read.

A signed 64-bit float number.

RangeError: Thrown if the byteOffset is 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.

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.getFloat64(0); // 0
