DataView.prototype.getBigInt64()
The getBigInt64() method gets a signed 64-bit integer
(long long) at the specified byte offset from the start of the DataView.
Try it
Syntax
getBigInt64(byteOffset)
getBigInt64(byteOffset, littleEndian)
Parameters
byteOffset-
The offset, in bytes, from the start of the view to read the data from.
littleEndianOptional-
Indicates whether the 64-bit int is stored in little- or big-endian format. If
falseorundefined, a big-endian value is read.
Return value
A BigInt.
Errors thrown
RangeError-
Thrown if the
byteOffsetis set such that it would read beyond the end of the view.
Description
There is no alignment constraint; multi-byte values may be fetched from any offset.
Examples
Using the getBigInt64 method
const buffer = new ArrayBuffer(8);
const dataview = new DataView(buffer);
dataview.getBigInt64(0); // 0n
