Behavior by question type
 * 1) Default:  If the subject enters a value that is not a number, that value is immediately cleared from the text box so that the subject can enter an appropriate value.
 * 2) Array (Texts): If the numbers only option is disabled, the "Show totals for" and "Show grand total" options will be overruled, while the total text boxes will not be displayed.
 * 3) Equation: Enabling this option will force the equation results to be converted to a numeric value. If the equation result is not a number (and not blank), the equation will return NaN, being saved as an empty string in the response table.
