DataView.prototype.setBigInt64()

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

Syntax

setBigInt64(byteOffset, value)
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 is 2n ** (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 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.
