API specification¶

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 bepositional-only parameters. SeeFunction and method signatures.

• When a function signature includes a*, optional parameters must bekeyword-only arguments. SeeFunction and method signatures.

• Broadcasting semantics must follow the semantics defined inBroadcasting.

• Unless stated otherwise, functions must support the data types defined inData 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. SeeData Type Categories.

• Unless stated otherwise, functions must adhere to the type promotion rules defined inType 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 inAccuracy.
