MATHEMATICA IMPORT/EXPORT FORMAT

# Bit

Uniform sequence of bits.
Binary data format.
• Import can read any file as a sequence of single bits.
• Export writes a list of 0s and 1s to a binary file.

## Import and ExportImport and Export

• Import["file", "Bit"] imports an arbitrary file as a sequence of bits, returning a packed array of 0s and 1s.
• Export["file", list, "Bit"] exports a list of 0s and 1s to a binary sequence of bits.
• Import["file", {"Bit", elem}] or Import["file", elem ] imports the specified element from file.
• Import["file", {"Bit", {elem1, elem2, ...}}] imports multiple elements.
• See the reference pages for full general information on Import and Export.
• ImportString and ExportString support the Bit 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 single bits (0 or 1)
• By default, Import and Export use the element.
• Import["file", {"Bit", n}] gives the n bit from file.
• Export["file", list, "Bit"] pads list with zeros at the end if the number of bits to be exported is not a multiple of 8.

## OptionsOptions

• Import option:
•  "HeaderBytes" 0 how many bytes to skip at the beginning of the file

### Basic Examples (1)Basic Examples (1)

Convert a text string to a list of bits:

 Out[1]=

Convert a list of 0s and 1s:

 Out[2]=

Export automatically pads with 0s if necessary:

 Out[3]=
