Here are some examples: WebBasic types¶ The most basic types can be expressed through simple expressions. The symbols below refer to attributes of the main numba module (so if you read “boolean”, it means that symbol can be accessed as numba.boolean). Many types are available both as a canonical name and a shorthand alias, following Numpy’s conventions.
