What will be the output of the function call = FLOOR(3.7, 2) in MS-Excel 2019?

Appeared in: NHM UP Staff Nurse-2023 Shift-2nd

Explanation

The FLOOR function in MS Excel rounds a number down to the nearest specified multiple.
The syntax is FLOOR(number, significance). Here, the number is 3.7 and the significance is 2.
The function finds the multiples of 2 (e.g., 0, 2, 4, 6...).
It then selects the largest multiple of 2 that is less than or equal to 3.7.
The multiple of 2 just below 3.7 is 2, so the function returns 2.

Option A: The number 3 is not a multiple of the specified significance, which is 2. The FLOOR function always returns a multiple of the significance argument.
Option C: The value 0.7 represents the decimal portion of the original number 3.7. The FLOOR function deals with rounding the entire number, not extracting its decimal part.
Option D: The number 4 is the result of rounding 3.7 up to the nearest multiple of 2. The FLOOR function specifically rounds down.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain MS-Excel FLOOR function as background academic context rather than a clinical decision trigger.
While this is a non-clinical question, computer literacy, including proficiency in spreadsheet software like MS Excel, is a valuable skill for nurses.
Nurses may use Excel for administrative tasks, managing patient data, creating schedules, or tracking research data.
Understanding basic functions helps in organizing and analyzing data efficiently, which is crucial in modern healthcare settings.

How to Approach the Question

First, identify the function being used: FLOOR.
Understand the purpose of the FLOOR function: It rounds a number down to the nearest multiple of a given significance.
Identify the two arguments provided: the number (3.7) and the significance (2).
List the multiples of the significance (2): ..., 0, 2, 4, 6, ...
Find the largest multiple from this list that is less than or equal to the number (3.7).
In this case, 2 is less than 3.7, and 4 is greater. Therefore, the function rounds down to 2.
