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));

Tests:

Power function (small number)
smallNumber*smallNumber;
Power function (large number)
largeNumber*largeNumber;
Power function (very large number)
veryLargeNumber*veryLargeNumber;
Square root function (small number)
Math.sqrt(smallNumber);
Square root function (large number)
Math.sqrt(largeNumber);
Square root function (very large number)
Math.sqrt(veryLargeNumber);
