BigIntwith Math Operators

We can use most of the math operators with BigInt just like we do with numbers, for example.


              
1

            
console.log(11n + 22n);
copy

A BigInt number and a regular number cannot be used together for performing some arithmetic operations, for example.


              
1

            
console.log(100n + 200);
copy

For this, we have to convert the number into a BigInt number explicitly by calling the BigInt(), for example.


              
123

            
let bigint = 100n;
let number = 200;
console.log(bigint + BigInt(number));
copy

Tarefa

A BigInt number named bigNumber with the assigned value of 12345n has been given to you. Your task is to:

  • Create a new variable named number and store 55 in it.
  • Convert the number to a BigInt number using the BigInt() function and store the result again in number.
  • Display the sum of these values.
