Question

So I am writing a javascript application, and basically if one number is greater than another I want to swap their values:

if(price1 > price2)
{
  var temp = price1;
  price1 = price2;
  price2 = temp;
}

This works fine up until a certain point, but once the numbers starting getting larger, i.e.:

price1: 12345678
price2: 234556

Then the expression will evaluate to false and will do nothing. Does anyone know what the issue is? Thanks!

Answer 1

Are you sure these are being compared as numbers? For example, if you change the code to

if (+price1 > +price2) {
    var temp = price1;
    price1 = price2;
    price2 = temp;
}

does it work? If so price1 and price2 are strings and the prefix + converts them to numbers.
