nptype
nptype is a term encountered in some numerical computing discussions to denote a numeric type used by array-oriented libraries, especially in generic or templated code. It functions as a placeholder for a concrete numeric dtype—such as an integer type (int32, int64), a floating type (float32, float64), or a complex type (complex128)—that a function or data structure should operate on. The exact meaning of nptype is not fixed, and its interpretation depends on the library or project.
In practice, nptype is often used in abstract interfaces or wrappers to indicate that a parameter can
Usage examples are typically in pseudocode: function scale(x: nptype, s: nptype) -> nptype: return x * s. In
Caution is warranted because nptype is not a standardized term across libraries. Rely on explicit dtype specifications
