Below are examples of the Number Positive_INFINITY property.

Example 1: In this example, we will print Infinity on the console.

let a = Number.POSITIVE_INFINITY;
console.log(a * 10);

Output:

Infinity

Example 2: When we multiply any positive number including Number.POSITIVE_INFINITY by Number.POSITIVE_INFINITY the result is Number.POSITIVE_INFINITY. 

let a = Number.POSITIVE_INFINITY;

console.log(a * 2);

Output:

Infinity

Example 3: When we multiply any negative number with Number.POSITIVE_INFINITY the result is negative Infinity. 

let a = Number.POSITIVE_INFINITY;
console.log(a * -2);

Output:

-Infinity

Example 4: When we divide any positive or negative number by Number.POSITIVE_INFINITY the result is 0. 

let a = Number.POSITIVE_INFINITY;

console.log(2 / a);

Output:

0

Example 5: When we multiply Number.POSITIVE_INFINITY by 0, result is NaN. 

let a = Number.POSITIVE_INFINITY;

console.log(a * 0);

Output:

NaN

Example 6: When we divide Number.POSITIVE_INFINITY by any negative number except Number.NEGATIVE_INFINITY, the result is Number.NEGATIVE_INFINITY. 

let a = Number.POSITIVE_INFINITY;

console.log(a / -2);

Output:

-Infinity

Example 7: When we divide Number.POSITIVE_INFINITY by any positive number except Number.POSITIVE_INFINITY, result is Number.POSITIVE_INFINITY. 

let a = Number.POSITIVE_INFINITY;

console.log(a / 2);

Output:

Infinity

Example 8: When we divide Number.POSITIVE_INFINITY by either NEGATIVE_INFINITY or POSITIVE_INFINITY, result is NaN. 

let a = Number.POSITIVE_INFINITY;
let b = Number.NEGATIVE_INFINITY;
