    random price from range of two values

    Hi there,

    Hope you can help? I am trying to write a function which returns a random price from between two other price values.

    i.e. if range is 10,000 and 60,000 then a random price might be 57,000??

    I havent coded anything as such yet, but I have been searching Google for help. And all the examples on there seem to deal with whole numbers no commas etc...

    So if anyone has a tutorial I could look at or maybe if you've done it before I would appreciate it if you could point me in right direction.

    Also in the example above im only using 5 digit numbers. But what if I wanted to increase the range and make the values higher??

    Thanks

    Code:
    function RandomMinMax(min,max){
     return min+Math.floor(Math.random()*(max-min));
    
    }
    
    
    alert(RandomMinMax(10000,60000));

    Actually, Vic's function should be like this:
    Code:
    function randomMinMax(min, max){
        return min+Math.floor(Math.random()*(max-min+1));
    }
    or else you will never get the max value (because Math.random() returns 0 <= n < 1 where n is the random number).

    Here's a related article
