QS:Numbers only

Numbers only (numbers_only)

Description

If you set this option the participant can only enter numbers in the text boxes.

For equation question types this setting indicates that the result will be a number only, not a string. This will guarantee proper calculations/conversion 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): Setting this to "No" will overrule "Show totals for" and "Show grand total" setting and total text boxes will not be displayed.
3. Equation: Setting this option to "Yes" will force 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.

Available options

• Yes
• No (default)
