Method for split display of quotient and remainder

Abstract

This invention relates to a quotient and arithmetical compliment split-screen display method, which tests the quotient and arithmetical compliment, wherein if the value digit number is small, then it is displayed by one screen; if it is large, then it is displayed by split screens. The invention can display the number on one screen due to the split screen function and switches the numbers through keys.

Description

technical field [0001] The invention relates to the technical field of electronic calculators, in particular to a split-screen display method for quotient / remainder suitable for electronic calculators. Background technique [0002] The electronic calculator is a good and accurate calculation aid. When performing arithmetic or logic operations, as long as the user provides sufficient parameters, the electronic calculator can output correct (or very close) results. [0003] Such as figure 1 As shown, the known electronic calculator 30 provides division operation (key ÷) and quotient / remainder operation (key / R). When the user inputs the dividend 2015 and the divisor 20, if the user presses the button ÷, the known electronic calculator 30 outputs 200.75 to the display screen 32; if the user presses the button / R, the known electronic calculator 30 is The quotient value 100 and the remainder 15 are output on the display screen 32 . Assuming that the effective number of digits...

Problems solved by technology

Assuming that the effective number of digits that the known electronic calculator 30 can express is 10 digits, the known electronic calculator 30 reserves, for example, 5 digits on the display screen 32 to display the quotient and the remainder respectively. Therefore, when the quotient / When calculating the remainder, if the effective digits of the quotient or the remainder are greater than 5 digits, the known electronic calculator 30 cannot display the quotient and the remainder at the same time (that is, the quotient or the remainder cannot be expressed only with 5 digits), so the known The electronic calculator 30 will directly change the quotient value / remainder operation into a division operation, and directly display the quotient obtained by the division operation on the display screen 32, instead of displaying the remainder. For example, the operation of 1234567÷11 is performed. 112233) is greater than 5 effective digits, therefore, the electronic calculator 30 will not display the result of the operation as 112233 remainder 4, but directly display the quotient value 112233.3636 obtained by the division operation, which is not the answer required by the user, which will cause the use of trouble
