Question

嗨，我试图收回BigDecimal唯一的数据。以下示例对我期望的内容进行成像

1.23 -> 123
123.99 -> 12399
1.345 -> 1345
0.23 -> 23

我尝试使用DecimalFormat，但我没有想法哪种模式是正确的。

import "angular-mocks/ngMock";
import * as angular from "angular";

import {inject, TestBed} from "@angular/core/testing";
import {Inject, Injectable, FactoryProvider} from "@angular/core";
import {AngularJSService} from "angularjs/angularjs.service" // angularjs service which is upgraded and injected in ExampleService angular service

// upgrading angular js service to make it possible to inject into angular services/components
const UpgradedProvider: FactoryProvider = {
  provide: AngularJSService,
  useFactory: ($injector: angular.auto.IInjectorService) => {$injector.get('AngularJSService')},
  deps: ['$injector']
};

// this is angular service which has upgraded angularjs service in dependency
@Injectable()
class ExampleService {
  public name: string = 'Example Service';

  constructor(angularJSService: AngularJSService) {
    // injecting angular js service
  }
}

describe('Angular Example Test Suite ', () => {
  let $injector: angular.auto.IInjectorService;

  beforeEach(() => {
    // init angular js module for test and define upgraded angular js service in this module
    angular.module('ExampleTest', []).service('AngularJSService', AngularJSService);
  });

  beforeEach(angular.mock.module('ExampleTest'));
  beforeEach(angular.mock.inject((_$injector_: ng.auto.IInjectorService) => {
    $injector = _$injector_;
  }));

  beforeEach(() => {
    TestBed.configureTestingModule({
      providers: [
        {
          provide: '$injector',
          useFactory: () => $injector,
          deps: []
        },
        UpgradedProvider,
        ExampleService
      ]
    });
  });

  it('should inject ExampleService', inject([ExampleService], (exampleService: ExampleService) => {
    chai.assert.isDefined(exampleService);
  }));
});

你可以将它转换为数字类型，但它有点危险，因为大小数可能是一个大数字，它可能不适合int。

如何将BigDecimal转换为没有分隔符的recievied数字
