getBigInt64(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
falseorundefined, a big-endian value is read.
- : optional Indicates whether the 64-bit int is stored in little- or big-endian format. If
Return value
