Is it possible to restrict the use of decimal values for spinners?

I had a customer order 1.5 pints of cream.  At first I thought it was a mistake on my end, but then I realized that they entered 1.5 into the spinner box.  99% of my customers just click the up or down arrows in the spinner, so this isn't a huge problem.  Regardless, shouldn't there be a check in place to prevent people from entering decimal values?

Thank you for reporting this to us.

Decimals are allowed on the spinners because there are cases where decimals can be needed for them. You can even put a decimal value in the stepping property in case you want to.

But, I think it would be a great addition to have the ability to force the use of integer values only. Thus, I've submitted a feature request on your behalf to ask for this implementation. Please note that we cannot assure that this will be actually implemented, but you will be notified here with any news we have on this matter.
