Javascript Question

parseFloat bug in IE

It seems a very simple question.
the result of parseFloat in IE is different from the results in Chrome and FF.
Here is the very simple code

var lat = parseFloat(" 25.482688176812758");

then try to open it in IE the alert is 25.482688176812757
but in chrome and FF is 25.482688176812758


It's the browser limitation of decimal places in implementation of Numbers.

A workaround is to use the library BigDecimal.
