UnsignedInteger32

Sequence of unsigned 32-bit integers.
Raw binary format.
Equivalent to the Byte format.
  • Import can read any file as a sequence of unsigned 32-bit integers.
  • Export writes a list of integers in the range to a binary file.

Import and ExportImport and Export

  • Import["file", "UnsignedInteger32"] imports any file, returning a packed array of integers in the range .
  • Export["file", list, "UnsignedInteger32"] exports a list of integers in the range .
  • Import["file", {"UnsignedInteger32", elem}] or Import["file", elem ] imports the specified element from file.
  • Import["file", {"UnsignedInteger32", {elem1, elem2, ...}}] imports multiple elements.
  • See the reference pages for full general information on Import and Export.
  • ImportString and ExportString support the UnsignedInteger32 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", {"UnsignedInteger32", n}] gives the n^(th) 32-bit integer from file.
  • Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.

OptionsOptions

  • General option:
  • ByteOrdering-1what byte ordering to use
  • Import option:
  • "HeaderBytes"0how many bytes to skip at the beginning of the file
