Detailed Description

Implementation of a floating point value.

The range of double values is system dependent as far as I know but should at least cover a "double" in C.

Constructor & Destructor Documentation

ulxr::Double::Double

(

)

Default constructor for a Double.

Definition at line 806 of file ulxr_value.cpp.

ulxr::Double::Double

(

double

d

)

Constructs a Double.

Parameters:

d

value for the construction

Definition at line 812 of file ulxr_value.cpp.

ulxr::Double::Double

(

const CppString &

s

)

Constructs a Double.

Parameters:

s

value for the construction as number string

Definition at line 824 of file ulxr_value.cpp.

References ulxr::getLatin1(), and val.

ulxr::Double::~Double

(

)

[virtual]

Destroys the Value.

Definition at line 819 of file ulxr_value.cpp.

Member Function Documentation

double ulxr::Double::getDouble

(

)

const

Returns the current value.

Returns:

current value

Definition at line 907 of file ulxr_value.cpp.

References ulxr::RpcDouble, and ULXR_ASSERT_RPCTYPE.

void ulxr::Double::setDouble

(

const double

newval

)

Sets a new content.

Parameters:

newval

the new content

Definition at line 914 of file ulxr_value.cpp.

References ulxr::RpcDouble, and ULXR_ASSERT_RPCTYPE.

ValueBase * ulxr::Double::cloneValue

(

)

const [virtual]

Creates a copy of the actual object.

Returns:

pointer to the copy

Implements ulxr::ValueBase.

Definition at line 831 of file ulxr_value.cpp.

References ulxr::RpcDouble, and ULXR_ASSERT_RPCTYPE.

CppString ulxr::Double::getSignature

(

bool

deep = false

)

const [virtual]

Returns the signature of value.

The signature consists of its type name.

Parameters:

deep

if nested types exist, include them

Returns:

The signature

Implements ulxr::ValueBase.

Definition at line 838 of file ulxr_value.cpp.

References ulxr::RpcDouble, and ULXR_ASSERT_RPCTYPE.

CppString ulxr::Double::getValueName

(

)

[static]

Returns the xml name of the Value.

Returns:

value name

Definition at line 845 of file ulxr_value.cpp.

References ULXR_PCHAR.

std::string ulxr::Double::getWbXml

(

)

const [virtual]

Returns the call as binary xml string.

The method call is converted to a wbxml sequence. It is prepended with the necessary xml procession instruction with version and encoding set to UTF-8.

Returns:

The wbxml content

Implements ulxr::ValueBase.

Definition at line 859 of file ulxr_value.cpp.

References ulxr::ApplicationError, ulxr::getWbXmlString(), ulxr::RpcDouble, ULXR_ASSERT_RPCTYPE, ULXR_GET_STRING, ulxr_i18n, ULXR_PCHAR, ulxr_snprintf, ulxr::ValueParserWb::wbToken_Double, ulxr::ValueParserWb::wbToken_Value, and ulxr::WbXmlParser::wbxml_END.

CppString ulxr::Double::getXml

(

int

indent = 0

)

const [virtual]

Returns the value as xml string.

The content and its type name is converted to an xml text. The structure of the text is indented to facilitate easy reading of larger blocks.

Parameters:

indent

current indentation level

Returns:

The xml content

Implements ulxr::ValueBase.

Definition at line 884 of file ulxr_value.cpp.

References ulxr::ApplicationError, ulxr::getXmlIndent(), ulxr::RpcDouble, ULXR_ASSERT_RPCTYPE, ULXR_GET_STRING, ulxr_i18n, ULXR_PCHAR, and ulxr_snprintf.

bool ulxr::Double::setScientificMode

(

bool

scientific

)

[static]

Switches the conversion mode for double values.

Large numbers create large strings for the number without necessarily increasing the accuracy. For that reason it is possible to switch to scientific mode which uses only the significant 15 or 16 digits.

• A floating point value using only digits and a decimal point like 1234567.890123. This is the default.
• Scientific mode with mantissa and exponent like 123.4567E12.

  Parameters:

  scientific

  true: use scientifiy mode like 123.456E-78

  Returns:

  the previous setting
