Detailed Description

template<typename T>
struct mi::base::numeric_traits_base< T >

Base class for the helper class to deduce properties of numeric types defined in this API.

This class provides the common default implementations of all member of numeric_traits, for its default template as well as all specialization. Thus, specializations just have to redefine what changes.

The default uses default constructed values. It therefore requires that a value of T can be default constructed.

Member Function Documentation

template<typename T>

static T mi::base::numeric_traits_base< T >::infinity ( ) throw ( )

inlinestatic

Returns an infinity value for T, if one exists, and T() otherwise.

template<typename T>

static T() mi::base::numeric_traits_base< T >::max ( ) throw ( )

inlinestatic

Returns the maximum finite value for T.

The value is equivalent to standard C constants CHAR_MAX, SHRT_MAX, FLT_MAX, DBL_MAX, etc.

Returns

the maximum finite value for T.

template<typename T>

static T() mi::base::numeric_traits_base< T >::min ( ) throw ( )

inlinestatic

Returns the minimum finite value for T; for floating point types, returns the minimum positive value.

The value is equivalent to standard C constants CHAR_MIN, SHRT_MIN, FLT_MIN, DBL_MIN, etc.

Returns

the minimum finite value for T.

template<typename T>

static T mi::base::numeric_traits_base< T >::negative_max ( ) throw ( )

inlinestatic

Returns the smallest finite negative value for T.

For signed integer types this value is typically (-max()-1). For unsigned integer types it is 0. For floating point types it is typically (-max()).

Returns

the smallest finite negative value for T.

template<typename T>

static T mi::base::numeric_traits_base< T >::quiet_NaN ( ) throw ( )

inlinestatic

Returns a quiet NaN value for T, if one exists, and T() otherwise.

template<typename T>

static T mi::base::numeric_traits_base< T >::signaling_NaN ( ) throw ( )

inlinestatic

Returns a signaling NaN value for T, if one exists, and T() otherwise.

Member Data Documentation

template<typename T>

const bool mi::base::numeric_traits_base< T >::has_infinity = false

static

Constant that is true if and only if T has an infinity representation.

You can get the infinity representation through the infinity() method.

template<typename T>

const bool mi::base::numeric_traits_base< T >::has_quiet_NaN = false

static

Constant that is true if and only if T has a quiet NaN (not-a-number) representation.

You can get the quiet NaN representation through the quiet_NaN() method.

template<typename T>

const bool mi::base::numeric_traits_base< T >::has_signaling_NaN = false

static

Constant that is true if and only if T has a signaling NaN (not-a-number) representation.

You can get the signaling NaN representation through the signaling_NaN() method.

template<typename T>

const bool mi::base::numeric_traits_base< T >::is_specialized = false

static

Constant that is true if and only if this traits is specialized for T.
