Re: [fpc-pascal] OpenCL, Re: C Hex Float.
thanks for the reply Marco > I'm working in vision, and I'd be very interested in OpenCL headers. you can download converted headers from here: http://wnsoft.com/~dima/opencl.zip original c headers are available here: http://www.khronos.org/registry/cl/ cl.h and cl_platform.h is united into cl.pas file cl_gl.h is converted to cl_gl.pas. I did not tested anything, yet. Just made a straight c to pascal convertion. But, in theory, this should be enough. thanks, dmitry ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal

I think this way is done to make the floating point constants portable.

I tried to test with calculation, but it seems fpc/Delphi don't support that (something like: const x = -double($9abc) shl $12; // sign (mantisse) SHL exponent ) ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
[fpc-pascal] OpenCL, Re: C Hex Float.
Anyway. does FPC community need converted OpenCL headers? i'd like to share them. Should they be converted to the proper structure first (/src, make, fpmake)? there're only 2 files anyway. I still have not found any reasonable way to convet c-hex-float number to pascal. i'm not sure if it's nice (and cross-platform) to declare, something like this: const CL_FLT_MAX : double = double($); thanks, dmitry > Does anyone have an experience with converting hex-float numbers from > C to Pascal? > > CL_FLT_MAX 0x1.fep127f > CL_FLT_MIN 0x1.0p-126f > CL_FLT_EPSILON 0x1.0p-23f > CL_DBL_MAX 0x1.fp1023 > CL_DBL_MIN 0x1.0p-1022 > CL_DBL_EPSILON 0x1.0p-52 > > any suggestions? ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
