Use formulas in columns
Fusion Tables supports creating a new column populated with the result of a formula on numbers in other columns.
To create a new formula column, choose Edit > Change columns > New > Formula column.
Supported formulas include:
- basic operations: + - * /
cos() sin() power(base, exponent)
if (condition, then, else)
Use column names in the formula. Add single quotes around column names that include spaces or special characters. Separate a list of items with commas.
The formula will use the first column it finds of that name. To use a later column with the same name, provide an index number. For example, 'Year(2)' refers to the second column with name Year.
Example: basic operations
Imagine a table with number columns for time and distance. The new column should show the average speed (distance / time) for each row.
Choose Edit > Change columns > New > Formula column to create this new column. Name the new column “speed”. In the Formula box enter:
distance / time
then Save. The new column will contain the result of performing the formula for each row.
Imagine a table with star ratings from 1 to 5. You want to create a new column with a simpler rating: "1" if it has 4 or 5 stars, and "0" if it's not good. Remember formulas work with number columns, not text.
Here's the logic formula to write:
if ('star rating' > 3, 1, 0)
