Leverage the power of mathematical functions within Angular to convert numbers into integers

In my Angular 7 Typescript class, I have the following setup:

export class Paging {

  itemCount: number;
  pageCount: number;
  pageNumber: number;
  pageSize: number;    

  constructor(pageNumber: number, pageSize: number, itemCount: number) {

    this.itemCount = itemCount;
    this.pageCount = itemCount > 0 ? Math.ceil(itemCount / pageSize) : 0;
    this.pageNumber = pageNumber;
    this.pageSize = pageSize;

  }

}

I'm facing two issues:
1. How can I successfully import Math functions without encountering an error?
2. Is there a way to convert the calculation result from Math.ceil(itemCount / pageSize) into an integer?

Answer №1

In agreement with user184994's suggestion, simply eliminate the (number)
```
this.pageCount = itemCount > 0 ? Math.ceil(itemCount / pageSize) : 0;
```
The function Math.ceil rounds up to the nearest integer: number (It returns the smallest integer greater than or equal to its argument).

If you need to convert into numerical values:

let str2deci = parseInt('123', 10);

let num = Number('456');
