MATHEMATICA IMPORT/EXPORT FORMAT

# Integer24

Uniform sequence of signed 24-bit integers.
Binary data format.
• Import can read any file as a sequence of signed 24-bit integers.
• Export writes a list of integers in the range to a binary file.

## Import and ExportImport and Export

• Import["file", "Integer24"] imports an arbitrary file as a sequence of signed 24-bit integers, returning a packed array of integers in the range .
• Export["file", list, "Integer24"] exports a list of integers in the range to a sequence of binary 24-bit integers.
• Import["file", {"Integer24", elem}] or Import["file", elem ] imports the specified element from file.
• Import["file", {"Integer24", {elem1, elem2, ...}}] imports multiple elements.
• See the reference pages for full general information on Import and Export.
• ImportString and ExportString support the Integer24 format.

## ElementsElements

• 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", {"Integer24", n}] gives the n 24-bit integer.
• Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

## OptionsOptions

• 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 (1)Basic Examples (1)

Export a list of integers to a binary 24-bit representation:

 Out[1]=

In the previous output, each integer is represented by a sequence of 3 bytes:

 Out[2]=

Convert the binary data back to a list of integers:

 Out[3]=
