Technical Notes Database TN1209D.txt Using the 80X87 emulator in TPW. Category :Pascal Platform :All Product :Turbo Pascal 1.0 Description: Question: Must TPW a the math coprocessor? Answer: Windows implements its own 80x87 instruction emulator as a DLL that is loaded when an 80x87 instruction is detected. The reason that the '87 code generation is an option is speed: emulators are always slower than the real hardware, and slower than using the 6 byte reals. If you need double, or extended reals, or Comp integers, then you must turn on '87 code generation, and Windows will adjust itself to compensate if there is no '87 hardware when the program is running. You do not need a coprocessor to compile or run the program. Reference: 7/16/98 4:35:42 PM
