Syntax

dataview.setBigUint64(byteOffset, value [, littleEndian])

Parameters

byteOffset

The offset, in bytes, from the start of the view to store the data from.

value

The value to set as a BigInt. The highest possible value that fits in an unsigned 64-bit integer is 2n ** 64n - 1n (18446744073709551615n). Upon overflow, it will be zero (0n).

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 written.

Return value

undefined.

Errors thrown

RangeError

Thrown if the byteOffset is set such that it would store beyond the end of the view.

Examples

Using the setBigUint64 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setBigUint64(0, 3n);
dataview.getBigUint64(0); // 3n
