All,

To amplify Bob's comments ---

That is one of the situations with digital displays Vs. analog.
An analog display might show your an SWR of 1.55 (if you can interpolate 
the needle position) while the digital display resolution will show you 
either a 1.5 or a 1.6 indication - there is no way to show an in-between 
reading on a digital display.
