# Result Recording Guppy's `output` function supports booleans, unsigned integers (`nat`), and arrays of these values on H-Series. Signed integers (`int`) and their arrays are also accepted but errors can occur when their values become negative. See [Integers](integers.md) for the restrictions on integer values. ## Array results Source file: `guppy_examples/guppy-features/supported/result-arrays.py` ```{literalinclude} ../../guppy_examples/guppy-features/supported/result-arrays.py :language: python ```
