QS:Numbers only

数字のみ (numbers_only)

説明

このオプションをオンにすると、参加者はテキストボックスに数字のみ入力できるようになります。

For the equation question types, this setting indicates that the result could only be a number, not a string. This will guarantee proper calculations/conversions in follow-up equations regarding the decimal mark.

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.
