Detailed Description

Semantic Object Real.

A real number as a quad-precision floating-point number adhering to the IEEE 754-2008 standard,
featuring a 112-bit significand and a 15-bit exponent.
This format offers at least 33 bits of precision.

Invariant

None.

Constructor & Destructor Documentation

SOR() [1/2]

SOR::SOR ( const std::string &  p_s )

inlineexplicit

Ctor from a string representation.

Precondition

p_s format is a valid IEEE 128 bit float.

Parameters

[in]

p_s

The string to parse as float.

SOR() [2/2]

SOR::SOR ( __float128  p_r )

inlineexplicit

Ctor from a float.

Parameters

[in]

p_r

The float.

Member Function Documentation

dup()

SOR * SOR::dup ( ) const

inlineoverridevirtual

Creates a new instance as copy following the red book definition.

Returns

SO * ... A copy.

Implements SO.

equal()

bool SOR::equal ( const SO *  p_other ) const

inlineoverridevirtual

Checks if this SO is equal to another SO.

Equality means:
SOL und SOM are always equal.
For SOD, SOF and SOK, share_ptr<> points to the same object.
For SOA, share_ptr<> points to the same object, but empty arrays are equal nonetheless.
For SOO and SOo the function pointer must be the same.
Otherwise the value must be the same, even for SOS with shared_ptr<>.

Returns

bool ... true if the SO's are of the same type and equal

See also

Will be used directly and unchanged as operator eq

Parameters

[in]

p_other

The object to compare with.

Implements SO.

ge()

bool SOR::ge ( OpError &  p_ec, const SO *  p_other  ) const

inlineoverridevirtual

Greater or equal.

The redundancy between equal(), gt() and ge() is a matter of performance.

Parameters

[out]

p_ec

Error code.

Returns

bool ... true is comparable and ge.

Parameters

[in]

p_other

The object to compare with.

Reimplemented from SO.

gt()

bool SOR::gt ( OpError &  p_ec, const SO *  p_other  ) const

inlineoverridevirtual

Greater than.

The redundancy between equal(), gt() and ge() is a matter of performance.

Parameters

[out]

p_ec

Error code.

Returns

bool ... true is comparable and gt.

Parameters

[in]

p_other

The object to compare with.

Reimplemented from SO.

opequal()

std::string SOR::opequal ( ) const

overridevirtual

String representation of object for operators '=', 'cvs' and 'stack'. Reals are formated for output with a default precision of 10 digits.

The precision can be changed with the operator __rprecision.

Returns

std::string ... String representation of the real value.

Implements SO.

ot()

OTCode SOR::ot ( ) const

inlineoverridevirtual

Returns an OTCode.

A "manual" implementation of polymorphism, where C++-polymorphisms fail

Returns

OTCode ... The OTCode of the instance.

Implements SO.

reciprocal()

OpError SOR::reciprocal ( )

inline

In place reciprocal.

Returns

OpError::undefinedresult for real numbers too small to have a reciprocal;
OpError::success otherwise.

type()

std::string SOR::type ( ) const

inlineoverridevirtual

Returns a type name.

Returns

std::string ... The type name of the instance.

Implements SO.
