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)
Parameters
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
falseorundefined, a big-endian value is read.
- : optional Indicates whether the 64-bit float is stored in
little- or big-endian format. If
Return value
A signed 64-bit float number.
Errors thrown
RangeError- : Thrown if the
byteOffsetis set such as it would read beyond the end of the view.
- : Thrown if the
Description
There is no alignment constraint; multi-byte values may be fetched from any offset.
