[jQuery] Easing Plugin brakes on all methods based on Math.exp with jQuery 1.2.X

[jQuery] Easing Plugin brakes on all methods based on Math.exp with jQuery 1.2.X


Hello I just tested the The Excellent Easing Plugin from
http://gsgd.co.uk/sandbox/jquery.easing.php with jQuery 1.2.1. and
all methods work fine except:
expoin, expoinout, expoout
These methods use Math.exp:
expoout: function(x, t, b, c, d) {
            var flip = 1;
            if (c < 0) {
                flip *= -1;
                c *= -1;
            }
            return flip * (-Math.exp(-Math.log(c)/d * (t-d)) + c + 1) + b;
        }
I cannot figure out the problem, does anybody has an idea?
