Return from list the double value that has the highest absolute value, without making the return value absolute

Short of iterating the collection, is there a way to return the double in a set that has the highest absolute value without making the values in the set actually absolute?

double[] vals = new double[] { 2.3, 1.7, -3.8};

vals.Max(v => Math.Abs(v)); // This returns 3.8 instead of -3.8
