I tried this with my orp-1.0.9 and classpath 0.03 and could not
reproduce your error.

I compiled orp according to the instructions on our website in order
to use classpath natives.  I used the jikes 1.15b compiler which has
fixes for numerous float/double problems of some past versions.  

 orp-1.0.9/mains/orp/Linux/dbg/orp -classpath $CLASSPATH DoubleTest
.3 -> 0.3
