There are indeed subtle differences between the PS2 and the IEEE implementation. Try the 'EE Core User's Manual' (2nd Edition), Page 77, Chapter 4 'Floating-Point Unit (FPU)', section 4.8 'IEEE 754 Compatability' Cheers. --- Gareth White - Engine Programmer - Ratbag Pty Ltd Level 8, 63 Pirie Street, Adelaide, SA, Australia, 5000 Ph: +61 8 8223 5830, Fax: +61 8 8223 5746, Mob: 0403 942668 http://www.ratbaggames.com/ ----- Original Message ----- From: "Research (GameBrains)" <[email protected]> To: <[email protected]> Sent: Thursday, February 27, 2003 4:46 PM Subject: [GD-Consoles] PS2 floating point Hello, Our physics engine is experiencing some odd behavior on the PS2. We traced it to our resting contact force calculation where sometimes it seems the result is not quite right, but it works fine on other platforms. I don't know if it's an urban legend or what, but I have heard that the PS2 has some quirks with regard to floating point numbers and so I thought I would just ask and see if this is something I need to look at or not. If so, what are the differences between the PS2 IEEE implementation and is there a doc describing them?
