MATHEMATICA IMPORT/EXPORT FORMAT
Integer32
- Import can read any file as a sequence of signed 32-bit integers.
- Export writes a list of integers in the range
to a binary file.
- Import["file", "Integer32"] imports an arbitrary file as a sequence of signed 32-bit integers, returning a packed array of integers in the range
.
- Export["file", list, "Integer32"] exports a list of integers in the range
to a sequence of binary 32-bit integers.
-
- Import["file", {"Integer32", elem}] or Import["file", elem ] imports the specified element from file.
- Import["file", {"Integer32", {elem1, elem2, ...}}] imports multiple elements.
-
- See the reference pages for full general information on Import and Export.
- ImportString and ExportString support the Integer32 format.
- 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", {"Integer32", n}] gives the n
32-bit integer.
- Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.
- General option:
-
- Import option:
-
| "HeaderBytes" | 0 | how many bytes to skip at the beginning of the file |
Convert a list of integers to a string representing a sequence of binary 32-bit integers:
| Out[1]= |  |
Verify that the correct number of bytes was written:
| Out[2]= |  |
Convert the binary data back to an expression:
| Out[3]= |  |
Import the same data, assuming it represents an array of unsigned integers:
| Out[4]= |  |
