Unity - TMP Input Field : How to limit number of digits after decimal point in Decimal Type

Question

Is there any easy way to limit the number of digits after the decimal point with an TMP_InputField set at decimal type ?

For exemple, if the user type 12.347, I want the text to stop at 12.34

Thank you !

You can register to an event onValidateInput, parse the string to a float, and reformat it with $"{value:0.##}.

Thanks !! I will try this when I am at home. But it will change only when I will enter or leave the field, so I guess it’s impossible to limit it “in live” while the user is typing ? – Deltaaaa Aug 01 '22 at 18:12

EDIT: If anyone else is looking for the exact same thing as me, I succeeded by doing this little trick :

        if (_hasComa)
        {
            string[] charAfterComa = _inputField.text.Split(",");
            string strAfterComa = charAfterComa[1];

            for (int i = 0; i < strAfterComa.Length; i++)
            {
                if (i >= 2)
                {
                    int index = strAfterComa.LastIndexOf(strAfterComa[i]);
                    if (index >= 0)
                        strAfterComa = strAfterComa.Substring(0, index);
                }
            }

            _inputField.text = charAfterComa[0] + ',' + strAfterComa;
        }

You got an option in the text mesh pro input field for limiting the characters that players enter
