Does the Standard specify any minimum range or minimum
precision for the float, double and long double. I haven't
found anything in the Standard about it.

This is one of those cases where the C++ standard adopts the
requirements of the C standard without repeating the text.
Section 5.2.4.2 Numerical limits spells out the minimum ranges for all
integer and floating point types, and minimum precision and several
other important factors for the floating point types. An
implementation, C or C++, is required to document its implementation.
The section number is the same in both the older version of the C
standard which the C++ standard includes, and the current C standard.
