GREATERTHANEQUAL Function

Returns true if the first argument is greater than or equal to the second argument. Equivalent to the >= operator.

  • Each argument can be a literal Integer or Decimal number, a function returning a number, or a reference to a column containing numbers.

Since the function returns a Boolean value, it can be used as a function or a conditional.

注記

Within an expression, you might choose to use the corresponding operator, instead of this function. For more information, see Comparison Operators.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

In the town of Circleville, citizens are allowed to maintain a single crop circle in their backyard, as long as it confirms to the town regulations. Below is some data on the size of crop circles in town, with a separate entry for each home. Limits are displayed in the adjacent columns, with theinclusivecolumns indicating whether the minimum or maximum values are inclusive.

ヒント

As part of this exercise, you can see how to you can extend your recipe to perform some simple financial analysis of the data.

Transformation:

After the data is loaded into the Transformer page, you can begin comparing column values:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

LESSTHANEQUAL(Radius_ft,minRadius_ft)

Parameter: New column name

'tooSmall'

While accurate, the above transform does not account for the minInclusive value, which may be changed as part of your steps. Instead, you can delete the previous transform and use the following, which factors in the other column:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

IF(minInclusive == 'Y',LESSTHANEQUAL(Radius_ft,minRadius_ft),LESSTHAN(Radius_ft,minRadius_ft))

Parameter: New column name

'tooSmall'

In this case, the IF function tests whether the minimum value is inclusive (values of 10 are allowed). If so, the LESSTHANEQUAL function is applied. Otherwise, the LESSTHAN function is applied. For the maximum limit, the following step applies:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

IF(maxInclusive == 'Y', GREATERTHANEQUAL(Radius_ft,maxRadius_ft),GREATERTHAN(Radius_ft,maxRadius_ft))

Parameter: New column name

'tooBig'

Now, you can do some analysis of this data. First, you can insert a column containing the amount of the fine per foot above the maximum or below the minimum. Before the first derive command, insert the following, which is the fine ($15.00) for each foot above or below the limits:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

15

Parameter: New column name

'fineDollarsPerFt'

At the end of the recipe, add the following new line, which calculates the fine for crop circles that are too small:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

IF(tooSmall == 'true', (minRadius_ft - Radius_ft) * fineDollarsPerFt, 0.0)

Parameter: New column name

'fine_Dollars'

The above captures the too-small violations. To also capture the too-big violations, change the above to the following:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

IF(tooSmall == 'true', (minRadius_ft - Radius_ft) * fineDollarsPerFt, if(tooBig == 'true', (Radius_ft - maxRadius_ft) * fineDollarsPerFt, '0.0'))

Parameter: New column name

'fine_Dollars'

In place of the original "false" expression (0.0), the above adds the test for the too-big values, so that all fines are included in a single column. You can reformat the fine_Dollars column to be in dollar format:

Transformation Name

Edit column with formula

Parameter: Columns

fine_Dollars

Parameter: Formula

NUMFORMAT(fine_Dollars, '$###.00')

Results:

After you delete the columns used in the calculation and move the remaining ones, you should end up with a dataset similar to the following:

Location

fineDollarsPerFt

Radius_ft

minRadius_ft

minInclusive

maxRadius_ft

maxInclusive

fineDollars

House1

$30.00

Now that you have created all of the computations for generating these values, you can change values forminRadius_ft,maxRadius_ft, andfineDollarsPerFtto analyze the resulting fine revenue. Before or after the transform where you set the value for fineDollarsPerFt, you can insert something like the following:

Transformation Name

Edit column with formula

Parameter: Columns

minRadius_ft

Parameter: Formula

'12.5'

After the step is added, select the last line in the recipe. Then, you can see how the values in the fineDollars column have been updated.
