Get (pseudo) random number inside given interval

Here's a classic: getting a random number from between minimum and maximum values.

//Returns random number between min and max
function getRandomNumber(min,max)
{
    return Math.random()*(max-min)+min;
}

//Returns random integer between min and max
function getRandomInteger(min,max)
{
    return Math.floor(Math.random()*(max-min+1))+min;
}

The result is a pseudo-random number because it's seeding is based on current time.
