Detailed Description

       Part of std::numeric_limits.

       The static const members are usable as integral constant expressions.

       Note:
           This is a separate class for purposes of efficiency; you should only access these
           members as part of an instantiation of the std::numeric_limits class.

Member Data Documentation

   const int std::__numeric_limits_base::digits [static] The number of radix digits that be
       represented without change: for integer types, the number of non-sign bits in the
       mantissa; for floating types, the number of radix digits in the mantissa.
       Definition at line 197 of file limits.

   const int std::__numeric_limits_base::digits10 [static] The number of base 10 digits that can
       be represented without change.
       Definition at line 199 of file limits.

   const float_denorm_style std::__numeric_limits_base::has_denorm [static] See
       std::float_denorm_style for more information.
       Definition at line 238 of file limits.

   const bool std::__numeric_limits_base::has_denorm_loss [static] 'True if loss of accuracy is
       detected as a denormalization loss,
               rather than as an inexact result.' [18.2.1.2]/42

       Definition at line 241 of file limits.

   const bool std::__numeric_limits_base::has_infinity [static] True if the type has a
       representation for positive infinity.
       Definition at line 230 of file limits.

   const bool std::__numeric_limits_base::has_quiet_NaN [static] True if the type has a
       representation for a quiet (non-signaling) 'Not a Number.'
       Definition at line 233 of file limits.

   const bool std::__numeric_limits_base::has_signaling_NaN [static] True if the type has a
       representation for a signaling 'Not a Number.'
       Definition at line 236 of file limits.

   const bool std::__numeric_limits_base::is_bounded [static]"True if the set of values
       representable by the type is finite. All built-in types are bounded, this member would be
       false for arbitrary precision types. [18.2.1.2]/54
       Definition at line 249 of file limits.

   const bool std::__numeric_limits_base::is_exact [static] True if the type uses an exact
       representation. All integer types are exact, but not all exact types are integer. For
       example, rational and fixed-exponent representations are exact but not integer.
       [18.2.1.2]/15
       Definition at line 210 of file limits.

   const bool std::__numeric_limits_base::is_iec559 [static] True if-and-only-if the type adheres
       to the IEC 559 standard, also known as IEEE 754. (Only makes sense for floating point
       types.)
       Definition at line 245 of file limits.

   const bool std::__numeric_limits_base::is_integer [static] True if the type is integer. Is
       this supposed to be 'if the type is integral'?
       Definition at line 205 of file limits.

   const bool std::__numeric_limits_base::is_modulo [static] True if the type is modulo, that is,
       if it is possible to add two positive numbers and have a result that wraps around to a
       third number that is less. Typically false for floating types, true for unsigned integers,
       and true for signed integers.
       Definition at line 254 of file limits.

   const bool std::__numeric_limits_base::is_signed [static] True if the type is signed.
       Definition at line 201 of file limits.

   const bool std::__numeric_limits_base::is_specialized [static] This will be true for all
       fundamental types (which have specializations), and false for everything else.
       Definition at line 192 of file limits.

   const int std::__numeric_limits_base::max_exponent [static] The maximum positive integer such
       that radix raised to the power of (one less than that integer) is a representable finite
       floating point number.
       Definition at line 224 of file limits.

   const int std::__numeric_limits_base::max_exponent10 [static] The maximum positive integer
       such that 10 raised to that power is in the range of representable finite floating point
       numbers.
       Definition at line 227 of file limits.

   const int std::__numeric_limits_base::min_exponent [static] The minimum negative integer such
       that radix raised to the power of (one less than that integer) is a normalized floating
       point number.
       Definition at line 217 of file limits.

   const int std::__numeric_limits_base::min_exponent10 [static] The minimum negative integer
       such that 10 raised to that power is in the range of normalized floating point numbers.
       Definition at line 220 of file limits.

   const int std::__numeric_limits_base::radix [static] For integer types, specifies the base of
       the representation. For floating types, specifies the base of the exponent representation.
       Definition at line 213 of file limits.

   const float_round_style std::__numeric_limits_base::round_style [static] See
       std::float_round_style for more information. This is only meaningful for floating types;
       integer types will all be round_toward_zero.
       Definition at line 263 of file limits.

   const bool std::__numeric_limits_base::tinyness_before [static] True if tininess is detected
       before rounding. (see IEC 559)
       Definition at line 259 of file limits.

   const bool std::__numeric_limits_base::traps [static] True if trapping is implemented for this
       type.
       Definition at line 257 of file limits.
