UnsignedInteger64

Background & Context

- Sequence of unsigned 64-bit integers.
- Raw binary format.
- Equivalent to the Byte format.

Import["file","UnsignedInteger64"] imports any file, returning a packed array of integers in the range .
Export["file",list,"UnsignedInteger64"] exports a list of integers in the range to file.
Import["file",{"UnsignedInteger64",elem}] or Import["file",elem ] imports the specified element from file.
Import["file",{"UnsignedInteger64",{elem₁,elem₂,…}}] imports multiple elements.
See the following reference pages for full general information:

	Import, Export	import from or export to a file
	CloudImport, CloudExport	import from or export to a cloud object
	ImportString, ExportString	import from or export to a string
	ImportByteArray, ExportByteArray	import from or export to a byte array

General Import elements:
"Elements" list of elements and options available in this file

"Summary" summary of the file

"Rules" list of rules for all available elements
Data representation element:
"Data" list of integers in the range
By default, Import and Export use the "Data" element.
Import["file",{"UnsignedInteger64",n}] gives the n 64-bit integer from file.
Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

Convert a list of integers to a string representing a sequence of binary 64-bit integers:

Verify that the correct number of bytes was written:

Convert the binary data back to a list of numbers:

Read the same binary data, assuming it represents signed integers:
