Description
The LESS OR EQUAL (<=) operator tests whether one value is less than or equal to another.
Usage
a <= b
Remarks
The value of the expression is TRUE if a is less than or equal to b.
Generally, a and b must have the same type. That is, a and b must both be numbers, or text, or dates. However, if either a or b are of different types, but one is text, then the other will be implicitly converted to text using the same conventions as the TEXT function.
When comparing text, the comparison is case sensitive. That means that "ABC" does not equal "abc".
Examples
Check if a respondent is an adult
If you have a quantity field collecting AGE, you cn determine whether the respondent is a minor with the following formula:
AGE <= 17
Compare text
You could use formulas to split participants into three groups based on their LAST_NAME:
IF(LAST_NAME <= "Q", "Third wave", IF(LAST_NAME <= "M", "Second wave", "First wave"))
Validate a date range
When collecting dates, you may want to ensure that they fall into a specific date range, for example between January 2022 and July 2023.
TRAINING_DATE >= DATE(2022,1,1) && TRAINING_DATE <= DATE(2023,7,31)
