Detailed Description
Implementation of miscellaneous definitionen und functions.
Function Documentation
◆ statistics()
| void statistics | ( | ) |
Dumps statistics data.
Dumps it only if there are open memory allocations.
- Note
- IDEA: a parameter "forcestatistics" and a command line option for ks to set it
◆ stofloat128()
| __float128 stofloat128 | ( | const std::string & | p_s | ) |
We need a dedicated function, because __float128 isn't supported by the standard library.
Implemented with GNU quadmath.
- Note
- IDEA: detailed description
- Returns
- __float128 the IEEE float
◆ stoint128()
| __int128 stoint128 | ( | const std::string & | p_s | ) |
We need a dedicated function, because __float128 isn't supported by the standard library.
Has no syntax check. A leading '+' is not allowed. No overflow check
- Note
- IDEA: define prerequisites.
- Returns
- __int128 ... the parsed integer
◆ to_string() [1/2]
| std::string to_string | ( | __float128 | r_ | ) |
We need a dedicated function, because __float128 isn't supported by to_string().
Implementation with GNU quadmath
- Returns
- std::string ... the string-representation of p_z
◆ to_string() [2/2]
| std::string to_string | ( | __int128 | p_z | ) |
We need a dedicated function, because __int128 isn't supported by to_string().
- Returns
- std::string ... the string-representation of p_z
- Parameters
-
[in] p_z we need a representation for this number
