Hello,
I try to tender keypad (numbers 0-9, decimal point and Enter), where I entered the number of floating point format float and the Enter key to send this number for further processing. Unfortunately, I do not know how to do it. Could someone help me.
Thanks in advance.

So I designed the keyboard. Just I do not know how to make entering a decimal point. Output need to max 1 of the fractional space.
Someone advise me?
I am sorry for my English.
Thank you.

You can use strings instead of integers and convert the string at the end back to floating point numbers

Thank you very much. Somehow I did not realize it.
