if the result e is less than 5, the number X to be displayed is reduced to the original number
After rounding off, the product is reduced to 10-decimalLengthObtaining a digit C after format conversion;
adding a unit of ten thousand to the digit C after format conversion;
judging the relation between the rounding result c and a count value i, wherein the count value i is defaulted to 0;
if the rounding result C is less than or equal to the counting value i, directly outputting the number C after the unit is added;
if the rounding result c is larger than the count value i, executing the following steps:
adding units of hundred million behind the number B or the number C after the adding unit of ten thousand;
adding 2 to the counting value to obtain a new counting value;
judging the relation between the rounding result c and the new count value i;
and if the rounding result C is larger than the new count value i, returning to the step of adding units of hundred million behind the number B or the number C after adding the units of ten thousand.
7. A digital display device, comprising:
the receiving module is used for receiving a request for displaying a user interface;
the first acquisition module is used for responding to the request and acquiring the number X to be displayed if the number needs to be displayed in the user interface;
the second acquisition module is used for acquiring an index a of 10 after the number X to be displayed uses a scientific counting method;
the first processing module is used for taking the number X to be displayed as an output result if the index a is less than or equal to 3;
the second processing module is used for determining the corresponding maximum counting unit when the number X to be displayed is displayed if the index a is larger than 3;
the third processing module is used for converting the number X to be displayed into an output result taking ten thousand as a counting unit if the corresponding maximum counting unit is ten thousand when the number X to be displayed is displayed;
the fourth processing module is used for converting the number X to be displayed into an output result taking the number hundred million or trillion as a counting unit if the corresponding maximum counting unit is hundred million or trillion when the number X to be displayed is displayed;
and the output module is used for displaying the output result on the user interface.
8. The digital display apparatus of claim 7, further comprising:
the third acquisition module is used for acquiring a first decimal decimalLength after the decimal point which needs to be reserved after the conversion of the number X to be displayed;
and the fifth processing module is used for defaulting to reserve a second decimal if the first decimal decimalLength after the decimal point which needs to be reserved after the conversion of the number X to be displayed is not acquired.
9. A server, comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, the program or instructions, when executed by the processor, implementing the steps of the digital exhibition method of claims 1-6.
10. A readable storage medium, on which a program or instructions are stored, which, when executed by a processor, carry out the steps of the digital exhibition method according to claims 1-6.
