Function Documentation

BtoStr()

std::string CppTools::BtoStr

(

const bool

val

)

Converts bool into std::string.

Parameters

[in]	val	bool variable
[out]	boolalpha	string variable that is either "true" or "false"

DtoStr()

std::string CppTools::DtoStr	(	const double	val,
		const int	precision = 2 )

Converts double to std::string with the given precision.

Parameters

[in]	val	value to be converted
[in]	precision	floating point precision
[out]	string	converted into string value

RemoveObsoletePrecision() [1/2]

std::string CppTools::RemoveObsoletePrecision

(

const double

value

)

Converts to std::string and removes every 0 until first non-zero value from right to left after the dot.

Example: if the value is 5.240100 the function will return "5.2401"

Parameters

[in]	value	variable to be converted and "trimmed" of the obsolete precision
[out]	str	input variable with obsolete precision removed

RemoveObsoletePrecision() [2/2]

std::string CppTools::RemoveObsoletePrecision

(

std::string

str

)

Removes every 0 until first non-zero value from right to left after the dot.

Example: if the value is "5.240100" the function will return "5.2401"

Parameters

[in]	str	string representation of floating point variable
[out]	str	input variable with obsolete precision removed

utf8_strlen()

int CppTools::utf8_strlen

(

const std::string &

str

)

Returns the length of the std::string type variable.

Parameters

[in]	str	stringh the length of which will be returned
[out]	length	the length of the passed string
