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.
Background & Context

-
- Uniform sequence of signed 32-bit integers.
- Binary data format.
Import & Export

- 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 following reference pages for full general information:
-

Import Elements

- 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",{"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.
Options

- General option:
-
ByteOrdering $ByteOrdering what byte ordering to use - Import option:
-
"HeaderBytes" 0 how many bytes to skip at the beginning of the file
