I'm stumped on a seemingly simple format issue for Power BI. I'm trying to format the remainder of a number into a custom fraction (13ths)

For example 755.38 should show as 755 **5/13**

In Excel, I use the custom fraction formula "# #/13"

In DAX I'm using the FORMAT function with the format as "#. #/13".

This just takes the remainder and displays it with a "/13" on the end. it does not divide the remainder correctly.

Example 755.38 is showing as 755. **4/13** when the correct calculation is 755 5/13
