template<class T >

string util::StringFactory::floatToString ( const T  xd, const int  width, const int  precision, const char  format  )

inlinestaticprotected

Convert float/double to string

Parameters

format,:

char to select the floatfield format flag 'd': default floating-point notation 'f': fixed-point notation 'e': scientific notation

References error_text, and factory_text.

template<class T >

string util::StringFactory::intToString ( const T  xd, const int  width  )

inlinestaticprotected

References error_text, and factory_text.

static void util::StringFactory::changeFormat ( ostringstream &  s, const char  format  )

staticprotected

set the floatfield format flag

Parameters

s,:	ostringstream where to write
format,:	char to select the floatfield format flag 'd': default floating-point notation 'f': fixed-point notation 'e': scientific notation

static string util::StringFactory::toString ( const double  xd, const int  width = DBL_DIG+7, const int  precision = DBL_DIG, const char  format = 'd'  )

static

Convert number to string

Parameters

format,:

(for double and float only) char to select the floatfield format flag 'd': default floating-point notation 'f': fixed-point notation 'e': scientific notation

static string util::StringFactory::toString ( const float  xd, const int  width = FLT_DIG+7, const int  precision = FLT_DIG, const char  format = 'd'  )

static

static string util::StringFactory::toString ( const long  xd, const int  width = ((sizeof(long)*8)/3)+1  )

static

static string util::StringFactory::toString ( const int  xd, const int  width = ((sizeof(int)*8)/3)+1  )

static

static string util::StringFactory::toMinSecString ( const double  xd, const int  precision = 0  )
