如何在Angular 6的数字类型的输入框中允许最大0到100的负值和正值？

Question

HTML代码<input type="number" min="0" max="100" required placeholder="Charge" [(ngModel)]="rateInput" name="rateInput" [formControl]="rateControl">

打字稿验证this.rateControl = new FormControl("", [Validators.max(100), Validators.min(0)]);

这将只允许正值。如果我们需要验证正值和负值0到100怎么办？

check number field added here

<input type="number" required min="-100" max="400" ng-pattern="/^[0-9]+$/" >
