Greetings! This is another post highlighting a beast mode from my Domo IDEAs conference session. This one covers how to format numbers a number in an abbreviated format.
Problem:
When concatenating a string with a number the resulting value is a string and unable to utilize Domo's built in formatting.
Solution:
This version only needs to check for length in increments of 3 to determine the correct units (Billions, Millions etc). The case statement goes in a descending order because the case statement will enter the condition that evaluates to true first. So every condition below the top one implies that the first condition is false.

-- Description: Since the numbers are being concatenated with a string
-- Default Domo number formatting is no longer possible. This will format the
-- total of the `random_number` field based on how large the number is.
-- ROUND will format the abbreviation to 2 decimal places.
CONCAT(
'Total: ',
-- CASE statements will evaluate the first expression it finds to be true and then exists.
-- No further conditions are evaluated
-- If >= 10 digits then it's in the billions
-- It would need to be expanded to 13 for (T)rillions
CASE WHEN LENGTH(ROUND(SUM(`random_number`), 0)) >= 10 THEN
CONCAT(ROUND(SUM(`random_number`) / 1000000000, 2), 'B')
-- 7 digits means Millions
WHEN LENGTH(ROUND(SUM(`random_number`), 0)) >= 7 THEN
CONCAT(ROUND(SUM(`random_number`) / 1000000, 2), 'M')
-- 4-6 digits = thousands
WHEN LENGTH(ROUND(SUM(`random_number`), 0)) >= 4 THEN
CONCAT(ROUND(SUM(`random_number`) / 1000, 2), 'K')
WHEN LENGTH(ROUND(SUM(`random_number`), 0)) <= 3 THEN
ROUND(SUM(`random_number`), 0)
WHEN SUM(`random_number`) IS NULL THEN 0
ELSE ''
END
)
Note:
These beast modes only go to 100 Billion (12 digits). Any number higher would need to expand using the same logic for higher lengths.
