Static Functions

denorm_min Returns the smallest nonzero denormalized value.
digits Returns the number of radix digits that the type can represent without loss of precision.
digits10 Returns the number of decimal digits that the type can represent without loss of precision.
epsilon Returns the difference between 1 and the smallest value greater than 1 that the data type can represent.
has_denorm Tests whether a type allows denormalized values.
has_denorm_loss Tests whether loss of accuracy is detected as a denormalization loss rather than as an inexact result.
has_infinity Tests whether a type has a representation for positive infinity.
has_quiet_NaN Tests whether a type has a representation for a quiet not a number (NAN), which is nonsignaling.
has_signaling_NaN Tests whether a type has a representation for signaling not a number (NAN).
infinity The representation for positive infinity for a type, if available.
is_bounded Tests if the set of values that a type may represent is finite.
is_exact Tests if the calculations done on a type are free of rounding errors.
is_iec559 Tests if a type conforms to IEC 559 standards.
is_integer Tests if a type has an integer representation.
is_modulo Tests if a type has a modulo representation.
is_signed Tests if a type has a signed representation.
is_specialized Tests if a type has an explicit specialization defined in the template class numeric_limits.
max Returns the maximum finite value for a type.
max_exponent Returns the maximum positive integral exponent that the floating-point type can represent as a finite value when a base of radix is raised to that power.
max_exponent10 Returns the maximum positive integral exponent that the floating-point type can represent as a finite value when a base of ten is raised to that power.
min Returns the minimum normalized value for a type.
min_exponent Returns the maximum negative integral exponent that the floating-point type can represent as a finite value when a base of radix is raised to that power.
min_exponent10 Returns the maximum negative integral exponent that the floating-point type can represent as a finite value when a base of ten is raised to that power.
quiet_NaN Returns the representation of a quiet not a number (NAN) for the type.
radix Returns the integral base, referred to as radix, used for the representation of a type.
round_error Returns the maximum rounding error for the type.
round_style Returns a value that describes the various methods that an implementation can choose for rounding a floating-point value to an integer value.
signaling_NaN Returns the representation of a signaling not a number (NAN) for the type.
tinyness_before Tests whether a type can determine that a value is too small to represent as a normalized value before rounding it.
traps Tests whether trapping that reports on arithmetic exceptions is implemented for a type.
