Creation

Creating a number is easy, it can be done just like for any other variable type using the var keyword.

Numbers can be created from a constant value:

  1. // This is a float:
  2. var a = 1.2;
  4. // This is an integer:
  5. var b = 10;

Or from the value of another variable:

  1. var a = 2;
  2. var b = a;

{% exercise %}
Create a variable x which equals 10 and create a variable y which equals a.
{% initial %}
var a = 11;
{% solution %}
var a = 11;

var x = 10;
var y = a;
{% validation %}
assert(x === 10 && y === a);
