    This file contains the actual implementations of the various
    ndarray operators.

    These are the upcasting rules of the binary operators

    - if complex is supported, and if one of the operarands is a complex, the result is always complex
    - if both operarands are real one of them is a float, then the result is also a float
    - operation on identical types preserves type

    uint8 + int8 => int16
    uint8 + int16 => int16
    uint8 + uint16 => uint16
    int8 + int16 => int16
    int8 + uint16 => uint16
    uint16 + int16 => float
