Greetings! This is another post highlighting a beast mode from my Domo IDEAs conference session. This one covers how to format numbers a number when concatenating with a string.

Problem:

Conditionally color a number based on a specific condition

Solution:

We can utilize the <div> and <span> tags with some CSS styling code to specify some color and conditionally combine those with a color value using CASE and CONCAT

-- Description: Use a CASE statement to conditionally color even numbers as green and odd numbers as red
-- MOD([VALUE], 2) returns the remainder of dividing the [VALUE] by 2. 0 for even and 1 for odd.
-- The coloring is using <div> and <span> with styling to perform the colorization
-- Note: This only works with an HTML table card.
CONCAT('<div><span style="color: ',
CASE WHEN MOD(FLOOR(SUM(`random_number`)), 2) = 0 THEN 'green' ELSE 'red' END,
  '">',
  FLOOR(SUM(`random_number`)),
  '</span></div>')
 

Note:

Because HTML coding / tags are being utilized an HTML table is the only card which will support this.
