Typedef Documentation

Difference

using mi::Difference = typedef Sint64

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.

Float32

using mi::Float32 = typedef float

32-bit float.

Float64

using mi::Float64 = typedef double

64-bit float.

Sint16

using mi::Sint16 = typedef short

16-bit signed integer.

Sint32

using mi::Sint32 = typedef int

32-bit signed integer.

Sint64

using mi::Sint64 = typedef long long

64-bit signed integer.

Sint8

using mi::Sint8 = typedef signed char

8-bit signed integer.

Size

using mi::Size = typedef Uint64

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.

Uint16

using mi::Uint16 = typedef unsigned short

16-bit unsigned integer.

Uint32

using mi::Uint32 = typedef unsigned int

32-bit unsigned integer.

Uint64

using mi::Uint64 = typedef unsigned long long

64-bit unsigned integer.

Uint8

using mi::Uint8 = typedef unsigned char

8-bit unsigned integer.

Enumeration Type Documentation

Comparison_result

enum mi::Comparison_result : Sint32

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

binary_cast()

template<class Target , class Source>

Target mi::base::binary_cast ( Source const &  val )

inline

Cast an immutable 'Source' value to an immutable 'Target' value.

Use this function as follows:

float  fval( 0.0f );
Uint32 uval( binary_cast<Uint32>(fval) );

operator-()

Comparison_result mi::operator- ( Comparison_result  sign )

inline

Reverses the sign of a three valued enum.

three_valued_compare()

template<typename T>

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

inline

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

Precondition

Values of type T must be comparable.

Note

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

three_valued_sign()

template<typename T>

Comparison_result mi::three_valued_sign ( T  t )

inline

Returns the three valued sign for a numerical type T.

Precondition

The value of type T must be comparable against 0.

Note

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