How do I reset the min value in a numeric control to -Inf

[imanon]

   SetCtrlVal(panel, PANEL_NUMERIC, 123.45);
   
   SetCtrlAttribute(panel, PANEL_NUMERIC, ATTR_MAX_VALUE, DBL_MAX);
   SetCtrlAttribute(panel, PANEL_NUMERIC, ATTR_MIN_VALUE, -DBL_MAX);
   
   GetCtrlVal(panel, PANEL_NUMERIC, &doub);
   
   fprintf (stderr, "value: %f\n", doub);

Constants (as opposed to functions) are available in C99 for several values, including FP_INFINITE, FP_NAN, etc.

But, NI doesn't provice a C99 compliant compiler, rather it's a C89 compiler.

A related issue is that in C89 you must use a constant as an intializer.  In C99 you could use a function to initialize a value to, say infinity, but then you wouldn't have to because you could use the constant 😉

This problem keeps coming up.  There are several troublesome areas cleaned up in C99.  I think NI should release a C99 compliant compiler for CVI.
