hi there!

this does not work well at all... (at least in IE6)

alert(12347 - 12345.01)

instead of returning 1.99 (like any well-behaved parser!!!!) it returns some crap (I forgot wich one)

anybody got any clue??

thanks

For me it returned 1.98999999997817 (IE6)

thanks for the tip! this one I knew already. the question is:


WHY IS THIS???

I find the same kind of problem:

Try this:
var A = Math.floor(8.70*100);
var B = Math.floor(870);
alert("A=" +A+ "\nB=" +B);

Return:
A= 869
B= 870

We meet this problem in C language.
This is seems to be a problem between Float and Integer….
But we didn't find a good solution…

Good luck

Hi all,
Nothing strange here, it should be this way. The program returns some values of calculation, and now it's your turn to handle them.

The solution is very simple: round the result to some decimal point. I wrote such a script where you can set the precision. It was posted here:

good luck

It's returning that weird value because the calculation is being done in BINARY rather than decimal, and certain decimal numbers do not have a finite representation in binary. Tracy Dryden
