| 2 | ; point constants in IEEE hex format. This also checks that the disassembler, |
| 3 | ; when presented with a FP constant that cannot be represented exactly in |
| 4 | ; exponential form, outputs it correctly in hex format. This is a distillation |
| 5 | ; of the bug that was causing the Olden Health benchmark to output incorrect |
| 6 | ; results! |
