Detailed Description

Long double.

This class is a wrapper for the long double primitive.

Version

1.0

Constructor & Destructor Documentation

LongDouble() [1/3]

LongDouble::LongDouble ( )

inlinenoexcept

Initializes the value as zero.

LongDouble() [2/3]

LongDouble::LongDouble ( long double  _value )

inlinenoexcept

Initializes the long double with the specified value. Implicit initialization is allowed.

Parameters

value

The desired value.

LongDouble() [3/3]

LongDouble::LongDouble ( const LongDouble &  copy )

inlinenoexcept

Initializes the value by other value.

Member Function Documentation

getEpsilon()

static long double LongDouble::getEpsilon ( )

staticnoexcept

The difference between 1 and the least value greater than 1 that is representable in the given floating point type.

getInfinity()

static long double LongDouble::getInfinity ( )

inlinestaticnoexcept

Returns infinity.

getMaximum()

static long double LongDouble::getMaximum ( )

staticnoexcept

Maximum representable finite floating-point number (2^e_max).

getMinimum()

static long double LongDouble::getMinimum ( )

staticnoexcept

Minimum normalized positive floating-point number (2^(e_min-1)).

getNaN()

static long double LongDouble::getNaN ( )

inlinestaticnoexcept

Returns quiet NaN. Signaling NaN should be avoided due to platform inconsistencies.

getSign()

long double LongDouble::getSign ( ) const

inlinenoexcept

Returns the sign.

getValue()

long double LongDouble::getValue ( ) const

inlinenoexcept

Returns the value of the long double.

isInfinity()

bool LongDouble::isInfinity ( ) const

inlinenoexcept

Returns true if the value is either +INFINITY or -INFINITY.

isNaN()

bool LongDouble::isNaN ( ) const

inlinenoexcept

Returns true if the value is Not a Number (NaN).

isNegative()

bool LongDouble::isNegative ( ) const

inlinenoexcept

Returns true if the value is negative.

isOrdinary()

bool LongDouble::isOrdinary ( ) const

inlinenoexcept

Returns true if the value is an ordinary number (not infinity or NaN).

isQuiteNaN()

bool LongDouble::isQuiteNaN ( ) const

inlinenoexcept

Returns true if the value is a quite NaN. A NaN that behaves predictably and does not raise exceptions in arithmetic operations is called a quiet NaN.

isSignalingNaN()

bool LongDouble::isSignalingNaN ( ) const

inlinenoexcept

Returns true if the value is a signaling NaN. A NaN that generally raises an exception when encountered as an operand of arithmetic operations is called a signaling NaN.

operator long double()

LongDouble::operator long double ( ) const

inlinenoexcept

Casts value to the long double primitive.

operator=() [1/2]

LongDouble& LongDouble::operator= ( const LongDouble &  assign )

inlinenoexcept

Assignment of value by value.

operator=() [2/2]

LongDouble& LongDouble::operator= ( long double  value )

inlinenoexcept

Assignment of this value by long double primitive.

setValue()

void LongDouble::setValue ( long double  value )

inlinenoexcept

Sets the value of the long double.

Parameters

value

The desired value.

Member Data Documentation

value

long double LongDouble::value = 0
