DataView.prototype.getBigUint64()

The getBigUint64() method gets an unsigned 64-bit integer (unsigned long long) at the specified byte offset from the start of the DataView.

Syntax

getBigUint64(byteOffset)
getBigUint64(byteOffset, littleEndian)

Parameters

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

Return value

A BigInt.

Errors thrown

  • RangeError
    • : Thrown if the byteOffset is 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.
