NAME¶
std::__numeric_limits_base -SYNOPSIS¶
Inherited by std::numeric_limits< _Tp >.Static Public Attributes¶
static constexpr int digits
Detailed Description¶
Part of std::numeric_limits.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¶
constexpr int std::__numeric_limits_base::digits [static]¶
The number of @c 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 201 of file limits.
constexpr int std::__numeric_limits_base::digits10 [static]¶
The number of base 10 digits that can be represented without change. Definition at line 204 of file limits.constexpr float_denorm_style std::__numeric_limits_base::has_denorm [static]¶
See std::float_denorm_style for more information. Definition at line 258 of file limits.constexpr bool std::__numeric_limits_base::has_denorm_loss [static]¶
<em>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 262 of file limits.
constexpr bool std::__numeric_limits_base::has_infinity [static]¶
True if the type has a representation for positive infinity. Definition at line 247 of file limits.constexpr 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 251 of file limits.
constexpr 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 255 of file limits.
constexpr bool std::__numeric_limits_base::is_bounded [static]¶
<em>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 271 of file limits.
constexpr bool std::__numeric_limits_base::is_exact [static]¶
True if the type uses an exact representation. <em>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 223 of file limits.
constexpr 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 266 of file limits.
constexpr 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 217 of file limits.constexpr bool std::__numeric_limits_base::is_modulo [static]¶
True if the type is @e 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 277 of file limits.
constexpr bool std::__numeric_limits_base::is_signed [static]¶
True if the type is signed. Definition at line 213 of file limits.constexpr 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 196 of file limits.
constexpr int std::__numeric_limits_base::max_digits10 [static]¶
The number of base 10 digits required to ensure that values which
differ are always differentiated. Definition at line 209 of file limits.
constexpr int std::__numeric_limits_base::max_exponent [static]¶
The maximum positive integer such that @c radix raised to the power of
(one less than that integer) is a representable finite floating point number. Definition at line 240 of file limits.
constexpr 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 244 of file limits.
constexpr int std::__numeric_limits_base::min_exponent [static]¶
The minimum negative integer such that @c radix raised to the power of
(one less than that integer) is a normalized floating point number. Definition at line 231 of file limits.
constexpr 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 235 of file limits.
constexpr 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 227 of file limits.
constexpr 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 288 of file limits.
constexpr bool std::__numeric_limits_base::tinyness_before [static]¶
True if tininess is detected before rounding. (see IEC 559) Definition at line 283 of file limits.constexpr bool std::__numeric_limits_base::traps [static]¶
True if trapping is implemented for this type. Definition at line 280 of file limits.Author¶
