Hi Barry.
Thanks for the detailed feedback you provided.
You are currently trying to grab decimal values without setting the step propriety.
Step is one of the parameters of the component that defines the interval at witch the items are separated in the slider and is set to 1 by default. As example demonstrated in our official documentation, by setting the step option to 10, the slider increases in steps of 10.
I would recommend you to select 0.1 as the value of the step property in order to achieve the behavior you are expecting.
Thank you for your patience.
Kind regards,
Simão Nunes.
