Description
Technical field
The present invention relates to a kind of calculating device capable of displaying constant and method thereof, particularly about a kind of typical value that can directly import constant, or by the calculation element (as counter GENERAL TYPE counter, engineering type counter or PDA, mobile phone, translation machine on) of page turning inquiry to demonstrate constant numerical value, unit and symbol.
Background technology
Counter is because the demand of computation process will be built in counter in physical constant (PhysicalConstant) commonly used or the physics astronomical constants (Physical Astronomical Constant) at present.Therefore can allow the user when carrying out the calculation of calculating formula, and can access the definition value of physical constant or physics astronomical constants fast for the user, to save time because of inquiry physical constant or physics astronomical constants.
And for the interior counter that has physical constant or physics astronomical constants (hereinafter to be referred as constant), when the user wants to access the definition value of constant, this constant of input is stored in the typical value (ITUMNUMBER) in the counter earlier, pushes the display screen that execute key (const key) just can be shown in the definition value of constant counter again.
Seeing also Fig. 1 is to be the operational flowchart of constant input, includes the following step:
Step 41: input typical value;
Step 42: judge whether to finish the typical value input;
If then skip to step 43;
If not, rebound step 41 then;
Step 43: judge whether to push const key;
If skip to step 44;
If not, skip to step 46;
Step 44: whether the numerical value of judging the input typical value surpasses 136; Wherein 136 is for being stored in the total value of counter internal constant,
If skip to step 47;
If not, skip to step 45;
Step 45: show constant numerical value
Step 46: enter the arithmetical logic computing unit;
Step 47: counter shows ERROR.
For example: if light velocity c (the Speed of Light Vacuum) typical value in the counter internal constant is 1.When wanting to access the constant of light velocity c, user's input 1 earlier pushes execute key (const key) again, and the numerical value that the display screen of counter promptly can demonstrate light velocity c is 299792458.
Yet in above-mentioned input process, the user must know the numerical value of constant representative in counter earlier, and the typical value of common constant can be inquired about the operation manual or the attached index card that is used for inquiring about the constant typical value of giving of counter.Therefore the user is when the input constant, and process not only bothers, and last counter also only demonstrates the numerical value or the conventional letter (is c as the light velocity) of constant, there is no Faxian the unit of constant or the numerical value of this representative in calculating of constant are shown.If operation manual or index card are lost, then the user can't correctly import constant.
So as from the foregoing, the aforementioned calculation device obviously has inconvenience and disappearance when the actual use of input constant, await being improved.
The inventor with not enough, proposes a kind of " calculating device capable of displaying constant and method thereof " reasonable in design at shortcoming of the prior art.
