# Data Types and Structs

These examples show the data-shape patterns that are currently practical for H-Series targets.

## Numeric types

Source file: `guppy_examples/guppy-features/supported/num-types.py`

```{literalinclude} ../../../guppy_examples/guppy-features/supported/num-types.py
:language: python
```

This page is especially useful for the current float caveat: constant float values are fine, but runtime float arithmetic is not supported on H-Series.

## Tuples

Source file: `guppy_examples/guppy-features/supported/guppy-tuple.py`

```{literalinclude} ../../../guppy_examples/guppy-features/supported/guppy-tuple.py
:language: python
```

This example stays within the supported subset by doing tuple-oriented bulk operations under `@guppy.comptime`.

## Structs

Source file: `guppy_examples/guppy-features/supported/guppy-struct.py`

```{literalinclude} ../../../guppy_examples/guppy-features/supported/guppy-struct.py
:language: python
```

This example is a good pattern to prefer over runtime arrays when you want a fixed-size register-like object in supported H-Series code.
