Hi Ryan,
At some point you probably set the distance display to show one decimal place, from the default of 3 places.  Chimera automatically uses the same number of places when reporting the value to the Reply Log.  You can change the number of decimal places in the Distances tool (Tools… Structure Analysis… Distances).  I believe it automatically saves the value in your preferences file when you change it, i.e. it is remembered for subsequent uses of Chimera.

I hope this helps,
Elaine
