Section 18.2.1.5 starts out by saying that "All members shall be provided for all specializations." Then it goes on to show specializations for float and bool, where one member is missing.

I agree, just adding the comment that the exact number of decimal digits is digits * ln(radix) / ln(10), where probably this real number is rounded downward for digits10, and rounded upward for max_digits10 (when radix=10, then digits10=max_digits10). Why not add this exact definition also to the standard, so the user knows what these numbers exactly mean. Quote: Bo Persson --- --- [ comp.std.c++ is moderated.
