Possible Duplicate: Is floating-point math broken? Why does JavaScript screw up this simple math? console.log(.1 + .2) // 0.3000000000000004 console.log(.3 + .6) // 0.8999999999999999 The first example is greater than the correct result, while the second is less. ???!! How do you fix this? Do you have to always convert decimals into integers before performing operations? Do I only have to worry about adding (* and / don't appear to have the same problem in my tests)? I've looked in a lot of places for answers. Some tutorials (like shopping cart forms) pretend the problem doesn't exist and just add values together. Gurus provide complex routines for various math functions or mention JavaScript "does a poor job" in passing, but I have yet to see an explanation.
