API specification — Python array API standard 2024.12 documentation (original) (raw)

A conforming implementation of the array API standard must provide and support the APIs and behavior detailed in this specification while adhering to the following conventions.

• When a function signature includes a /, positional parameters must be positional-only parameters. See Function and method signatures.
• When a function signature includes a *, optional parameters must be keyword-only arguments. See Function and method signatures.
• Broadcasting semantics must follow the semantics defined in Broadcasting.
• Unless stated otherwise, functions must support the data types defined in Data Types.
• Functions may only be required for a subset of input data types. Libraries may choose to implement functions for additional data types, but that behavior is not required by the specification. See Data Type Categories.
• Unless stated otherwise, functions must adhere to the type promotion rules defined in Type Promotion Rules.
• Unless stated otherwise, floating-point operations must adhere to IEEE 754-2019.
• Unless stated otherwise, element-wise mathematical functions must satisfy the minimum accuracy requirements defined in Accuracy.
