    • console.log(Math.ceil(.95));
      // expected output: 1
      
      console.log(Math.ceil(4));
      // expected output: 4
      
      console.log(Math.ceil(7.004));
      // expected output: 8
      
      console.log(Math.ceil(-7.004));
      // expected output: -7
      

• Number.isInteger()

  • 　　The Number.isInteger() method determines whether the passed value is an integer.

  • function fits(x, y) {
      if (Number.isInteger(y / x)) {
        return 'Fits!';
      }
      return 'Does NOT fit!';
    }
    
    console.log(fits(5, 10));
    // expected output: "Fits!"
    
    console.log(fits(5, 11));
    // expected output: "Does NOT fit!"
