Multiplication 2 numbers is behaving strange

[jefbr]

Hi everybody!

This is either going to be "oh duh" or "oh god"... I just came back from a holiday. 🙂

While multiplying numbers, I'm sometimes getting "close" but wrong results.

Does anybody have experience with that?

See how 190*2.379 should be 452.01 and not 454.389?

This is the cleaned up code (I changed the numbers for readability) 

var theThing = {    x:100,
                    y:200,
                    w:300,
                    h:400,
                    gravity:{   x:100,
                                y:200
                            }
                };

var ratio = 2.379;

theThing.x *= ratio;
theThing.y *= ratio;
theThing.w *= ratio;
theThing.h *= ratio;
theThing.gravity.x *= ratio;
theThing.gravity.y *= ratio;

The data types are "number" not string (checked it)

Does anybody have any suggestion/lead/tip/link/pill?

Thanks a lot! ❤️

Hello? Is there anybody out there?

Just nod if you can hear me...

They're probably all just comfortably numb 😉

Goddammit! 😄

Your lips move but I can't hear what you're saying!

I'll need some information first
Just the basic facts

More for myself than anything else...

That image, and only that image, has a different size than all others in the collection I'm using for testing.

Key takeaway:

Before you throw an adobe at the wall, check your media as well as your script!
