octave-lyh: libinterp/interpfcn/data.cc annotate

annotate libinterp/interpfcn/data.cc @ 15213:336f42406671

use numeric_limits functions instead of DBL_MIN, DBL_MAX, etc. * __glpk__.cc, ls-mat5.cc, data.cc, ls-oct-ascii.h, pr-output.cc, lo-utils.cc: Replace all uses of DBL_MIN, DBL_MAX, DBL_EPSILON, FLT_MIN, FLT_MAX, and FLT_EPSILON with numeric_limits functions. * variables.h (set_internal_variable): Use +/- octave_Inf as default values for minval and maxval.
