Unable to call constructor, because parameter 2. Value 0,01 out of range 0,1 to 100 - error

I am getting this error when I create a KeyframeEase object

kfEaseObj.speed = 0;

kfEaseObj.influence = 0,01;

var ease = new KeyframeEase(Number(kfEaseObj.speed),Number(kfEaseObj.influence));

It's message is straight forward and is in compliance with the  AE Scripting Guide. At page 84 it states, that speed must be in range of 0,1 to 100. However, when I looked at some keyframe data I noticed that some keyframes have values out of this range.

Take a look at this image:

This is a valid AE scale keyframe. What is going on here? How is this an allowed keyframe influence value?

As always, thanks!
