Integer64

Uniform sequence of signed 64-bit integers.
Binary data format.
  • Import can read any file as a sequence of signed 64-bit integers.
  • Export writes a list of integers in the range to a binary file.
  • Import imports an arbitrary file as a sequence of signed 64-bit integers, returning a packed array of integers in the range .
  • Export exports a list of integers in the range to a sequence of binary 64-bit integers.
  • Import imports multiple elements.
  • See the reference pages for full general information on Import and Export.
"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
  • Import gives the n^(th) 64-bit integer.
  • Trailing bytes are ignored if the size of the imported file is not a multiple of the data size.
  • General option:
ByteOrdering-1what byte ordering to use
"HeaderBytes"0how many bytes to skip at the beginning of the file
Convert a list of integers to a string representing a sequence of binary 64-bit integers:
