Connected concepts

Limits and interpretation

  • Real sqrt, exp, ln, square, reciprocal and abs; unsupported operations and domain failures are refused.
  • Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.

Reference basis

This software operation and its numerical conventions are defined by the public contract and worked example; no external research result is claimed.

Implementation sources

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