Examples of report expressions for number questions are provided below.
Basic mathematical operators can be used with numerical questions, which can be used to add, subtract, multiply, divide, or find the modulus of the responses to these questions. The following are examples:
${number1 - 15}
${number1 * 6}
${number1 / number2}
${number1 % number2}
Tip:
If the expression includes a complex mathematical expression, consider using brackets to ensure that the report generation produces the result you expect.
For decimal questions, the round expression can be used to set a maximum number of decimal places to which the value is rounded. The following example rounds the number 3.141592 to the four decimal places of 3.1416:
${decimal1 | round:4}
The toFixed expression can be used to set a maximum number of decimal places to which the value is rounded. The following example fixes the number of decimal places in 3.14 to 3.140:
${decimal1 | toFixed:3}
You can use the format expression to display the response to a number question in a specific way using placeholder characters. The following placeholder characters are supported:
| Character | Description |
|---|---|
. | Decimal separator. |
, | If placed in the format expression, adds group separators, with group size determined by the number of digits between the first group separator placeholder and either the decimal point placeholder or the end of the expression. If not added, no group separators are used. |
0 | Required digits. If the response has fewer than the required number of digits, it will be padded with zeros. |
# | Optional digits. If the response has more than the provided number of digits, the number will be rounded. |
Tip:
The decimal and thousands separators will be displayed in the printed result based on the chosen locale.
The following example returns the response to a maximum of three decimal places with thousands separators, rounding if necessary:
${decimal1 | format:"#,##0.###"}
