Re: [Plplot-devel] D bindings (nearly finished) and tests on Mac OS X

[Arjen M. <arj...@de...>]

Hi Andrew,

I looked at the source code for the bindings and I realised that
currently we do not use tcl_precision or something similar to _return_ 
values from PLplot routines. Instead we simply use %f to format the
returned number. Up to now that was satisfactory, but the time functions
return data with high precision.

As a temporary workaround, could you try with a format like %.20f -
like:

Line 283, 284 in pltclgen.tcl:
     "PLFLT& {
          puts $GENFILE "    sprintf( buf, \"%.20f\", $argname($i) );"

(I seem to have added all manner of comments about it - never got around
to actually implement them. It was not pressing then. I will be glad
to take care of it myself, once I can comfortably access my computer
at home again)

Regards,

Arjen
