The getDecimalInfo function is used to get the decimal information of a number.
The getDecimalPlaces function is used to get the number of decimal places of a number.
The padZero function is used to pad a number with zeros to a specified number of decimal places.
The parseIdCard Parsing Chinese ID card information
Parameters
getDecimalInfo
value(number): The input number.
getDecimalPlaces
value(number): The input number.
padZero
value(number): The number to be padded.decimalLength(number): An optional parameter that specifies the number of decimal places. Default is 0.
parseIdCard
value(string): The ID card number to be parsed.
Returns
getDecimalInfo
- (DecimalInfo): An object that contains the decimal information of the input number.
getDecimalPlaces
- (number): The number of decimal places of the input number.
padZero
- (string): If no decimal places are specified, it returns the original number string. Otherwise, it returns the padded number string.
parseIdCard
- (IdCardInfo): An object that contains the information of the ID card number.
This interface represents the information of an ID card.
region(string): The region of the ID card holder.birthdate(string): The birthdate of the ID card holder in the format 'YYYY-MM-DD'.gender(string): The gender of the ID card holder. '男' for male and '女' for female.valid(boolean): Whether the ID card number is valid.
Usage
ts
import { getDecimalInfo, getDecimalPlaces, padZero, parseIdCard } from "pixiu-number-toolkit";
const value = 123.456;
const decimalInfo = getDecimalInfo(value);
console.log(decimalInfo);
// Outputs:
// {
// valueString: '123.456',
// decimalIndex: 3,
// decimalLength: 3,
// integerPart: '123',
// decimalPart: '456',
// integerLength: 3
// }
const decimalPlaces = getDecimalPlaces(value);
console.log(decimalPlaces); // Outputs: 3
const paddedValue = padZero(value, 5);
console.log(paddedValue); // Outputs: '123.45600'
