this last part from the parallax seven segment display tutorial

So I'm on this parallax tutorial:
https://learn.parallax.com/tutorials/language/propeller-c/propeller-c-simple-circuits/seven-segment-display

Is there a better code line to display the voltage value for the 7-segment display instead of this primitive stuff below?


I only have one segment display so there is no worry about the 10th decimal then.
