JavaScript has only one type of numbers. Numbers can be written with, or without decimals:
var x1 = 34.00; (Written with decimals)
var x2 = 34; (Written without decimals)
Extra large or extra small numbers can be written with scientific (exponential) notation:
var y = 123e5; (12300000)
var z = 123e-5; (0.00123)
