+; This testcase checks to make sure that the assembler can handle floating 
+; point constants in IEEE hex format. This also checks that the disassembler,
+; when presented with a FP constant that cannot be represented exactly in 
+; exponential form, outputs it correctly in hex format.  This is a distillation
+; of the bug that was causing the Olden Health benchmark to output incorrect
+; results!
