Can you identify this numerical category?

Can you identify this number type?

console.log(0100); // output 64
console.log(050); // output 40
console.log(010); // output 8

In a hexadecimal system, it would be:

0100 = 256
050 = 80
010 = 16

Answer №1

Those numbers are called octal numbers, also known as base 8.

Avoid using this syntax as it is not allowed in strict mode.

However, you can incorporate them into ES6/ES2015 with some adjusted syntax.

0o100; // 64
0o50;  // 40
0o10;  // 8
