So why not use a NumericUpDown instead?

Good idea! However, it only works for values arranged on uniform intervals, won't work for arbitrary values.

Sure they do, you can type in anything you want.

As far as I remember, it will be rounded to nearest value from the finite set of allowed values, otherwise it would defeat the purpose. This input type is very safe, does not require validation.

float.Parse("110.9") works perfectly fine.

Of course, but not for all cultures. In some, it's ','.

Yes, presumably the OP is in one where . is a decimal place holder since he is asking :)

What's worse, '.' could be used for "thousands separator", but parsing it need an option. That would be the solution, if this is so. I don't want to discuss anything until the inquirer clarifies cultural aspects and what's expected. (Bad question again...)

It should work. However, it depends on the current culture. What is it? Can be so happen that the decimal separator is ','? If it's '.', please show the example of input which you think should be correct.

See https://msdn.microsoft.com/en-us/library/2thct5cb(v=vs.110).aspx[^]. A better way is to use the TryParse method as shown at https://msdn.microsoft.com/en-us/library/26sxas5t(v=vs.110).aspx[^].
