Notes

  • All Labeled formats can be cast directly to integer within LSL
  • Full formats are optimal for fixed width viewing, or packing into raw strings.
  • Portable formats are designed for compatibility with outside systems that may use different bit lengths
  • Suggest using the smallest compiled version that fits your needs
