ROUNDUP

Rounds a number up, away from zero, to a certain precision.

Syntax:

ROUNDUP(number, places)

returns number rounded up (away from zero) to places decimal places. If places is omitted or zero, the function rounds up to an integer. If places is negative, the function rounds up to the next 10, 100, 1000, etc. This function rounds away from zero.

Example:

ROUNDUP(1.1111, 2)

returns 1.12

ROUNDUP(1.2345, 1)

returns 1.3

ROUNDUP(45.67, 0)

returns 46

ROUNDUP(-45.67)

returns -46

ROUNDUP(987.65, -2)

returns 1000

Application:

Calculating Materials for a Construction Project

Scenario: A construction company needs to order concrete bags for a new sidewalk project. The concrete is sold in bags that cover exactly 0.5 square meters. The company has calculated the total area of the sidewalk sections in square meters, and they need to determine the exact number of bags to order for each section.

Problem: Standard rounding might lead to ordering too few bags. For example, if a section requires 12.3 bags, rounding down to 12 would leave the company short. Even standard rounding to 12 would still be an underestimate. The company must always round up to ensure they have enough material to complete each section.

Solution: The ROUNDUP function is the perfect tool for this task. It rounds a number away from zero to the nearest specified multiple.

The formula would be: ROUNDUP(Area / Coverage_per_Bag, 0)

Area: The total area of a sidewalk section in square meters.
Coverage_per_Bag: The coverage provided by one bag, which is 0.5 square meters.
0: The number of decimal places to round to. In this case, we need to round to a whole number of bags, so we use 0.

Data and Calculation

Below is a representation of the data and the results of the ROUNDUP function.

	Sidewalk Section	Calculated Area (m2)	Bags Needed (Calculated)	ROUNDUP Formula	Bags to Order
	A	B	C	D	E
1	Main Path	12.75	25.5	ROUNDUP(12.75 / 0.5, 0)	26
2	Side Walk A	8.1	16.2	ROUNDUP(8.1 / 0.5, 0)	17
3	Side Walk B	10.4	20.8	ROUNDUP(10.4 / 0.5, 0)	21
4	Front Entrance	5	10	ROUNDUP(5.0 / 0.5, 0)	10

Explanation of the Results:

Main Path: The calculated need is 25.5 bags. Since you can't buy half a bag, the company must round up to the next whole number, which is 26. Using ROUNDUP ensures this.
Side Walk A: The calculated need is 16.2 bags. ROUNDUP correctly dictates that 17 bags must be ordered.
Side Walk B: The calculated need is 20.8 bags. The function rounds this up to 21 bags.
Front Entrance: The calculated need is exactly 10 bags. In this case, ROUNDUP does not change the value, as it is already a whole number. The company orders exactly 10 bags.

By using the ROUNDUP function, the construction company eliminates the risk of ordering insufficient materials, which would cause costly delays and additional shipping fees. This ensures that every project section has enough concrete to be completed on time.
