Slightly, but not entirely OT: I once encountered a similar situation when a program that ran smoothly on a real calculator (HP 29C) didn’t do on an emulated one. The program with a separation into individual digits from a fractional number worked fine thanks to the bcd construct of the (earlier) HP machines, but the emulator (on a pc in this case) uses binary, so that f x=y? may not correctly compare f.e. 0.1 from a calculation with 0.1 as a constant value anymore. The program filled the programming space entirely; there was no room for extra steps for a ‘better/safer’ comparison in the emulator. It took a long time to figure this out, I remember. Learnt to be careful with emulators. |
