Typedef Documentation

typedef Sint64 mi::Difference

Signed integral type that is large enough to hold the difference of two pointers.

It corresponds to a 32-bit signed integer on 32-bit architectures and a 64-bit signed integer on 64-bit architectures.

typedef float mi::Float32

32-bit float.

typedef double mi::Float64

64-bit float.

typedef signed short mi::Sint16

16-bit signed integer.

typedef signed int mi::Sint32

32-bit signed integer.

typedef long long mi::Sint64

64-bit signed integer.

typedef signed char mi::Sint8

8-bit signed integer.

typedef Uint64 mi::Size

Unsigned integral type that is large enough to hold the size of all types.

This type is for example used for dimensions and indices of vectors.

It corresponds to a 32-bit unsigned integer on 32-bit architectures and a 64-bit unsigned integer on 64-bit architectures.

typedef unsigned short mi::Uint16

16-bit unsigned integer.

typedef unsigned int mi::Uint32

32-bit unsigned integer.

typedef unsigned long long mi::Uint64

64-bit unsigned integer.

typedef unsigned char mi::Uint8

8-bit unsigned integer.

Enumeration Type Documentation

enum mi::Comparison_result

An enum for a three-valued comparison result.

The three values, -1, 0, and 1, have several symbolic names that can be used interchangeable depending on the context. The symbolic names group together as indicated in their order.

Enumerator
NEGATIVE	= -1. Sign of a value is negative.
ZERO	= 0. Value is zero.
POSITIVE	= +1. Sign of a value is positive.
LESS	= -1. First value is less than second value.
EQUAL	= 0. First value is equal to second value.
GREATER	= +1. First value is greater than second value.

Function Documentation

Comparison_result mi::operator- ( Comparison_result  sign)

inline

Reverse the sign of a three valued enum.

template<typename T >

Comparison_result mi::three_valued_compare ( T  lhs, T  rhs  )

inline

Return the three valued comparison result between two values of a numerical type T.

Values of type T must be comparable.

Note

The result of this function is undefined if lhs or rhs is NaN.

template<typename T >

Comparison_result mi::three_valued_sign ( T  t)

inline

Return the three valued sign for a numerical type T.

A value of type T must be comparable against 0.

Note

The result of this function is undefined if t is NaN.

Variable Documentation

const Difference mi::DIFFERENCE_MAX_VALUE = 9223372036854775807LL

static

The maximum value for Difference.

Note

The actual value of this constant depends on the architecture. Possible values are 9223372036854775807 on 64-bit architectures and 2147483647 on 32-bit architectures.

const Difference mi::DIFFERENCE_MIN_VALUE = -9223372036854775807LL - 1LL

static

The minimum value for Difference.

Note

The actual value of this constant depends on the architecture. Possible values are -9223372036854775808 on 64-bit architectures and -2147483648 on 32-bit architectures.

const Size mi::SIZE_MAX_VALUE = 18446744073709551615ULL

static

The maximum value for Size.

Note

The actual value of this constant depends on the architecture. Possible values are 18446744073709551615 on 64-bit architectures and 4294967295 on 32-bit architectures.
