The setBigInt64()
method stores a signed 64-bit integer (long long) value at the specified byte offset from the start of the DataView
.

Syntax
dataview.setBigInt64(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 a signed 64-bit integer is2n ** (64n -1n) - 1n
(9223372036854775807n
). Upon overflow, it will be negative (-9223372036854775808n
). - littleEndian
- Optional Indicates whether the 64-bit int is stored in little- or big-endian format. If
false
orundefined
, a big-endian value is written.
Return value
Errors thrown
RangeError
- Thrown if the
byteOffset
is set such that it would store beyond the end of the view.
Examples
Using the setBigInt64
method
var buffer = new ArrayBuffer(8); var dataview = new DataView(buffer); dataview.setBigInt64(0, 3n); dataview.getBigInt64(0); // 3n
