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.
