EXAMPLE - Comparison Functions Equal

This example demonstrate the following comparison functions.

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.

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 New formula
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 New formula
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 New formula
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 New formula
Parameter: Formula type Single row formula
Parameter: Formula IF((ISODD(sideA) == true) OR (ISODD(sideB) == true),TRUE,FALSE)
Parameter: New column name 'isSideOdd'
