Has anyone come across a problem with the IIT 2C87 coprocessor and gnuplot with 3D enhancements? The system is compiled with Turbo C 2.0; it crashes with a "Floating point error: Partial lost of precision" when the 2C87 is enabled (either through the compile time switch -f87 or the runtime switch set "87=Y".) Unfortunately, the executable distributed through simtel20, "gnuplot-3d", shows the same symptom. I bought the 2C87 just a week ago. It has dramatically speeded up all my other floating point intensive applications and has otherwise shown no incompatibilities. So, I am inclined to believe that the problem lies on the software side. BTW, gnuplot 2.2 runs just fine. Thanks in advance, Robert
