EXAMPLE - Comparison Functions Equal
This example demonstrates comparison functions.
Functions:
Item | Description |
---|---|
EQUAL Function | Returns |
NOTEQUAL Function | Returns |
ISEVEN Function | Returns |
ISODD Function | Returns |
In this example, the dataset contains current measurements of the sides of rectangular areas next to the size of those areas as previously reported. Using these functions, you can perform some light analysis of the data.
Source:
sideA | sideB | reportedArea |
---|---|---|
4 | 14 | 56 |
6 | 6 | 35 |
8 | 4 | 32 |
15 | 15 | 200 |
4 | 7 | 28 |
12 | 6 | 70 |
9 | 9 | 81 |
Transformation:
In the first test, you are determining if the four-sided area is a square, based on a comparison of the measured values for sideA
and sideB
:
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | EQUAL(sideA, sideB) |
Parameter: New column name | 'isSquare' |
Next, you can use the reported sides to calculate the area of the shape and compare it to the area previously reported:
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | NOTEQUAL(sideA * sideB, reportedArea) |
Parameter: New column name | 'isValidData' |
You can also compute if the reportedArea can be divided into even square units:
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | ISEVEN(reportedArea) |
Parameter: New column name | 'isReportedAreaEven' |
You can test if either measured side is an odd number of units:
Transformation Name | |
---|---|
Parameter: Formula type | Single row formula |
Parameter: Formula | IF((ISODD(sideA) == true) OR (ISODD(sideB) == true),TRUE,FALSE) |
Parameter: New column name | 'isSideOdd' |
Results:
sideA | sideB | reportedArea | isSquare | isValidData | isReportedAreaEven | isSideOdd |
---|---|---|---|---|---|---|
4 | 14 | 56 | FALSE | FALSE | TRUE | FALSE |
6 | 6 | 35 | TRUE | TRUE | TRUE | FALSE |
8 | 4 | 32 | FALSE | FALSE | TRUE | FALSE |
15 | 15 | 200 | TRUE | TRUE | TRUE | TRUE |
4 | 7 | 28 | FALSE | FALSE | TRUE | TRUE |
12 | 6 | 70 | FALSE | TRUE | TRUE | FALSE |
9 | 9 | 81 | TRUE | FALSE | FALSE | FALSE |
