Properties of fundamental types.Member Function Documentation¶
template<typename _Tp> static _Tp std::numeric_limits< _Tp >::denorm_min () throw () [inline], [static]¶
The minimum positive denormalized value. For types where @c has_denorm is false, this is the minimum positive normalized
value. Definition at line 300 of file limits.
template<typename _Tp> static _Tp std::numeric_limits< _Tp >::epsilon () throw () [inline], [static]¶
The machine epsilon: the difference between 1 and the least value greater than 1 that is representable. Definition at line 287 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::infinity () throw () [inline], [static]¶
The representation of positive infinity, if has_infinity. Definition at line 291 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::max () throw () [inline], [static]¶
The maximum finite value. Definition at line 284 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::min () throw () [inline], [static]¶
The minimum finite value, or for floating types with denormalization, the minimum positive normalized value. Definition at line 282 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::quiet_NaN () throw () [inline], [static]¶
The representation of a quiet 'Not a Number,' if has_quiet_NaN. Definition at line 293 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::round_error () throw () [inline], [static]¶
The maximum rounding error measurement (see LIA-1). Definition at line 289 of file limits.template<typename _Tp> static _Tp std::numeric_limits< _Tp >::signaling_NaN () throw () [inline], [static]¶
The representation of a signaling 'Not a Number,' if has_signaling_NaN. Definition at line 296 of file limits.Member Data Documentation¶
const int std::__numeric_limits_base::digits [static], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
"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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
True if the type is signed. Definition at line 201 of file limits.const bool std::__numeric_limits_base::is_specialized [static], [inherited]¶
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], [inherited]¶
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 224 of file limits.
const int std::__numeric_limits_base::max_exponent10 [static], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
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], [inherited]¶
True if trapping is implemented for this type. Definition at line 257 of file limits.Author¶
