Two signed32 inputs10 and20 pass; the output is10. Changing the second input to real-valued storage is rejected.

Connected concepts

Limits and interpretation

  • Type equality includes enumeration identity and scaled-integer metadata. Different quantities or dimensions may still be independent inputs; this is a numeric-type constraint.

Reference basis

This compiler and software type contract is defined by the documented behavior and executable example; no external research result or full external API parity is claimed.

Implementation sources

This reference follows the public interface and locally verified numerical checks for an upcoming release.
