How do i format numbers

Comma Separation Extension

Comma Spaces

1500 / 1000 =1.5
So all you would need to do is add K on end in text object
But i guess it would be problematic
BUT that you could deal with array

Where there is StrLength() expression which returns how many characters there are in string

So for example you have variable Cash
Cash = 1500
So StrLength(ToString(Cash)) = 4 cause there are 4 characters
Now there is expression StrRepeat()
So StrRepeat(0,StrLength(ToString(Cash))) would result in 0000
SOOOO StrRepeat(0,StrLength(ToString(Cash)-1)) would be 000
AND SOO ToNumber(1+StrRepeat(0,StrLength(ToString(Cash)-1))) would result in 1000
So now Cash / ToNumber(1+StrRepeat(0,StrLength(ToString(Cash)-1))) would result in 1.5
