Functions

  Type Name Description
Public function Static ULANG_FORCEINLINE constexpr T

Clamp ( const T X,
const T Min,
const T Max
)

 Clamps X to be between Min and Max, inclusive.
Public function Static double

Extensionalize ( double Value
)

  
Public function Static double

FloatAdd ( double Left,
double Right
)

 Arithmetic operations in a non-fast-math environment (IEEE compliant).
Public function Static double

FloatDivide ( double Left,
double Right
)

  
Public function Static bool

FloatEqual ( double Left,
double Right
)

 We use an ordering relationship different from the default IEEE float ordering (because we require NaNs to compare equal to each other).
Public function Static ULANG_FORCEINLINE bool

FloatGreater ( double Left,
double Right
)

  
Public function Static ULANG_FORCEINLINE bool

FloatGreaterEqual ( double Left,
double Right
)

  
Public function Static ULANG_FORCEINLINE double  
Public function Static bool

FloatIsFinite ( double Value
)

 Predicates for different FP specials.
Public function Static bool

FloatIsInfinite ( double Value
)

  
Public function Static bool

FloatIsNaN ( double Value
)

  
Public function Static bool

FloatLess ( double Left,
double Right
)

  
Public function Static bool

FloatLessEqual ( double Left,
double Right
)

  
Public function Static double

FloatMultiply ( double Left,
double Right
)

  
Public function Static ULANG_FORCEINLINE double  
Public function Static ULANG_FORCEINLINE bool

FloatNotEqual ( double Left,
double Right
)

  
Public function Static int64_t

FloatRanking ( double Value
)

 Ranking function that turns a double into an int64 that defines a total order compatible with the ordering implied for floats, to be precise
Public function Static double

FloatSubtract ( double Left,
double Right
)

  
Public function Static ULANG_FORCEINLINE constexpr bool

IsPowerOf2 ( const T X
)

 Checks if a number is a power of two.
Public function Static ULANG_FORCEINLINE float

Loge ( float Value
)

 Computes natural logarithm.
Public function Static ULANG_FORCEINLINE constexpr T

Max ( const T A,
const T B
)

 Returns higher value in a generic way.
Public function Static ULANG_FORCEINLINE constexpr T

Min ( const T A,
const T B
)

 Returns lower value in a generic way.
Public function Static ULANG_FORCEINLINE double

ReinterpretInt64AsDouble ( uint64_t Int
)

 FP special constants: NaN and infinity.
Public function Static double

ToFloat ( int64_t Value
)
