UnsignedInteger128

• Import can read any file as a sequence of unsigned 128-bit integers.

• Export writes a list of integers in the range to a binary file.

IMPORT AND EXPORT

• Import["file", "UnsignedInteger128"] imports any file, returning a packed array of integers in the range .

• Export["file", list, "UnsignedInteger128"] exports a list of integers in the range to file.

• Import["file", {"UnsignedInteger128", elem}] or Import["file", elem ] imports the specified element from file.

• Import["file", {"UnsignedInteger128", {elem₁, elem₂, ...}}] imports multiple elements.

• See the reference pages for full general information on Import and Export.

• ImportString and ExportString support the UnsignedInteger128 format.

ELEMENTS

• General Import elements:

	"Elements"	elements and options available in this file
	"Rules"	full rules for each element and option
	"Options"	rules for options, properties, and settings

• Data representation element:

"Data"

list of integers in the range

• By default, Import and Export use the "Data" element.

• Import["file", {"UnsignedInteger128", n}] gives the n 128-bit integer from file.

• Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

OPTIONS

• General option:

ByteOrdering

-1

what byte ordering to use

• Import option:

"HeaderBytes"

0

how many bytes to skip at the beginning of the file

Basic Examples

Convert a list of integers to a string representing a sequence of binary 128-bit integers: In[1]:= Out[1]= In the previous output, each exported integer is taking up 16 bytes: In[2]:= Out[2]= Convert the binary data back to an expression: In[3]:= Out[3]= Import the same data, assuming it represents signed integers: In[4]:= Out[4]=
