when I use parseFloat method to convert a string to a number,it seems this method doest works well.
e.g.
var str="12121212121212122.44";
when called:
parseFloat(str);
it returns 12121212121212122.45
but if it's the below case:
var str="1212121212121212.44";//note:it's 16 digits now
then:
parseFloat(str);
this will return the correct value 1212121212121212.44
is this a bug or javascript engine problem, or something else?
Reproducible: Always
sorry, what I mean the total digits is mainly talking about the integer section ,not including the decimal section.
