Script Preparation code:

// Javascript uses floats for numbers. Generaate some numbers in advance.
var smallNumber = Math.pow(2, 7) + Math.floor(Math.random() * Math.pow(2,7));
var largeNumber = Math.pow(2, 30) + Math.floor(Math.random() * Math.pow(2,30));
var veryLargeNumber = Math.pow(2, 60) + Math.floor(Math.random() * Math.pow(2,60));
