MATHEMATICA IMPORT/EXPORT FORMAT
UnsignedInteger128
Sequence of unsigned 128-bit integers.
Raw binary format.
Equivalent to the Byte format.
Raw binary format.
Equivalent to the Byte format.
- 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
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.

Basic Examples (1)
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]= |  |
