    [0017] FIG. 8 is a schematic of relevant internals of any of the calculators of FIGS. 1-7.

    [0018] FIG. 9 is a schematic of an alternative embodiment of a calculator having a base-12 interface, with a number key configure to represent 3.663, another number key configured to represent 6.336, another number key configured to represent 10.sub.base 10, and another number key configured to represent 11.sub.base 10.

    DETAILED DESCRIPTION

    [0019] The following discussion provides many example embodiments of the inventive subject matter. Although each embodiment represents a single combination of inventive elements, the inventive subject matter is considered to include all possible combinations of the disclosed elements. Thus, if one embodiment comprises elements A, B, and C, and a second embodiment comprises elements B and D, then the inventive subject matter is also considered to include other remaining combinations of A, B, C, or D, even if not explicitly disclosed.

    [0020] FIG. 1 depicts an embodiment of a calculator having interface 100 with various function keys, a period key, and thirteen number keys. The number keys are used to input the usual one through nine digits, an additional number key that uses the symbol custom-character to represent PHEO (3.664), another number key that uses the symbol custom-character to represent SIEV (6.336), and another number key that uses the symbol custom-character to represent NULL (9.999). Although not shown, the calculator has a physical or virtual toggle to switch between custom-character representing zero and representing 9.999.

    [0021] All of the keys of FIG. 1, as well as FIGS. 2-7 and 9 herein, should be interpreted generically as being implemented in any combination of hard (physical) and soft (virtual) keys. Similarly, the calculators of FIGS. 1-7 and 9 should be interpreted generically as any of a stand-alone calculator, an iPad or other tablet, a laptop or desk top computer, and so forth. Thus, the entirety of what is displayed in FIGS. 1-7 and 9 should be viewed as the front view of a hand-held calculator, and alternatively viewed as a window on a display screen of a larger device.

    [0022] FIG. 2 is very similar to FIG. 1, except that here the symbol has been replaced by the term PHEO (3.664), the symbol has been replaced by the term SIFcustom-character (6.336), there is a designated zero key, and the symbol custom-character custom-character (9.999) has been replaced by the term NULL.

    [0023] FIG. 3 is also similar to FIG. 1, except that here the symbol custom-character has been replaced by the * sign is used to represent PHEO (3.664), and the # to represent SIEV (6.336), and the symbol custom-character (9.999) has been replaced by a designated zero key.

    [0024] FIG. 4 is also similar to FIG. 1, except that here the symbol custom-character has been relocated to the lower left corner of the interface 400, the symbol custom-character relocated to the lower right corner of the interface 400, and a zero key used to represent zero or 9.999.

    [0025] FIG. 5 is also similar to FIG. 1, except the zero key is relocated to the bottom right corner of the interface 500, and is used to represent zero or 9.999.

    [0026] FIG. 6 depicts another embodiment of FIG. 1, except that here the symbol custom-character has been replaced by the value 3.663, and the symbol custom-character has been replaced by the value 6.336, and the symbol has been replaced by a zero key to represent zero or 9.999.

    [0027] FIG. 7 is similar to FIG. 1, except that here the symbol custom-character has been replaced by the term 10.sub.base 10 to represent PHEO (3.664), and the symbol custom-character has been replaced by the term 11.sub.base 10 to represent SIEV (6.336), and the symbol custom-character (9.999) has been replaced by a designated zero key to represent zero or 9.999.

    [0028] FIG. 8 depicts relevant internals of the calculator of FIG. 1. Corresponding internals are contemplated for each of the interfaces of FIGS. 2-7.

    [0029] As depicted, interface 100 generally comprises a battery 125 or other power supply, a processor 127, power connectors 126, data connectors 128 to the input keys, and data connector 129 to the display area.

    [0030] FIG. 9 is a schematic of an alternative embodiment of a calculator having a base-12 interface, with a number key configure to represent 3.663, another number key configured to represent 6.336, another number key configured to represent 10.sub.base 10, and another number key configured to represent 11.sub.base 10.

    [0031] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the scope of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms comprises and comprising should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps can be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something designated from the group consisting of A, B, C . . . and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc.
