how to make shortened numbers

Take your string and convert it to a integer via 'Number from text' procedure block in the Math Menu. 

Take the integer and use if statements to determine the multiple, i.e. <=1000, <=1000000, etc. 

Divide the integer by the passing multiple from the if statement and then plug it into a rounding function to make the integer a whole value. 

You can then re-create the string using 'create text with' procedure block, from the text menu, by using the integer and a string to represent the multiple. i.e "M", "K", etc.

Hope this makes sense. You'd need to adjust it to better suit your needs though. I would send an image but I haven't figured out how to attach one yet.
