The 'Number' question type is used to enter numbers. In the question settings, under 'Answers', you can set the number of categories (1 or 2), the display of the unit field, and the width of the input field. In addition, in the settings under 'Limits', you can set the number of whole places, the number of decimal places, the minimum (Min) and maximum (Max) number that respondents can enter, and set a warning for exceeding the limit.

In the question settings, you can also select the 'Slider' layout, where the respondent does not enter a number, but instead uses the slider to select a number between the minimum and maximum.
