DOSBox Sees Continued Success

KingofGnG writes "DOSBox, the emulator designed to run DOS games on modern operating systems (and not necessarily on a PC), has been chosen as project of the month for May on SourceForge. It's the latest award granted to a piece of software that 'simply does what it is supposed to do,' as the authors say. After having amassed more than 10 million downloads, it will soon be getting an update that's been awaited for almost two years."

On x87, all floating point operations are done at 80-bit precision. On PowerPC, they are done at either 32-bit or 64-bit. If you do a 32-bit float operation in C and compile it for x87[1] then you will get a load-and-sign-extend operation turning it into an 80-bit float then operate on that, and finally truncate it when you write it out. Compile the same code for PowerPC and you will get a 32-bit load, 32-bit operations, and a 32-bit store. If you perform a sequence of calculations then the rounding errors will accumulate a lot faster on PowerPC than x87.

    DOSBox probably could use PowerPC long double (128-bit) floats to get around this (which works great until you find someone who was relying on rounding errors from 80-bit operations), but that's going to be a lot slower, which is more likely to generate complaints from gamers than the odd rounding error.
