Function Documentation

◆ log()

__float128 log ( __float128 p_num )

__float128 overload of log()

Precondition: p_num > 0

◆ log10()

__float128 log10 ( __float128 p_num )

__float128 overload of log10()

Precondition: p_num > 0

◆ mmod()

__int128 mmod	(	__int128	p_x,
		__int128	p_m
	)

inline

Mathemtical modulus.

different from C++ 11 and newer, which define the calculation of a remainder such that (a/b)*b + ab = a

◆ pow()

__float128 pow	(	__float128	p_base,
		__float128	p_exp
	)

__float128 overload of pow()

Precondition: p_exp == rint(p_exp) or p_base >= 0; p_base != 0 or p_exp != 0

◆ sqrt()

__float128 sqrt ( __float128 p_r )

__float128 overload of sqrt()

Precondition: p_r >= 0

◆ stofloat128()

__float128 stofloat128 ( const std::string & p_s )

We need an adapter function, because __float128 isn't supported by the standard library.

Implemented with GNU quadmath.

◆ stoint128()

__int128 stoint128 ( const std::string & p_s )

We need an adapter function, because __float128 isn't supported by the standard library.

Precondition: p_s format is: [-][digit]+; MIN_INT <= integer interpretation <= MAX_INT

Returns: __int128 ... the integer interpretation

◆ to_string() [1/2]

std::string to_string	(	__float128	p_float,
		size_t	p_precision
	)

We need an adapter function, because __float128 isn't supported by std::to_string().

Implementation with GNU quadmath.

Returns: std::string ... the string-representation of p_float

◆ to_string() [2/2]

std::string to_string ( __int128 p_z )

We need an adapter function, because __int128 isn't supported by std::to_string().

Parameters

[in] p_z we need a representation for this integer

Returns: std::string the string-representation of p_z
