A bug that occured recently. My newest example:

alert(2.3*1.15)

this should alert "2.645", but the massage is "2.6449999999999996". This error
occurs also in IE, and if I remember correctly also under Linux.

Reproducible: Always
Steps to Reproduce:
1. alert(2.3*1.15)

Actual Results:  
2.6449999999999996

Expected Results:  
2.645
See bug 5856 comment 1.

But note that you can use toFixed(2), e.g., to get good "dollars and cents"
results: click on javascript:alert((2.3*1.15).toFixed(2)) to see the result.
