c8::rational::rational

rational() noexcept;

Constructs a c8::rational with a value of zero.

Exceptions

None.

c8::rational::rational

rational(long long n, long long d) noexcept;

Constructs a c8::rational with a value of n/d.

Exceptions

None.

c8::rational::rational

rational(const integer &n, const integer &d);

Constructs a c8::rational with a value of n/d.

Exceptions

• std::bad_alloc in the event of a memory allocation failure.

c8::rational::rational

rational(double v) noexcept;

Constructs a c8::rational that represents the floating point value d.

Exceptions

• std::bad_alloc in the event of a memory allocation failure.

c8::rational::rational

rational(const std::string &v);

Constructs a c8::rational by parsing the string v. v must have the form n/d, where n and d are both integer values representing the numerator and denominator of the rational, respectively. Either or both may have a prefix of "0" for an octal value, or "0x" for a hexadecimal value. Either may also be prefaced with a '-' or '+' to indicate a negative or positive value respectively.

Exceptions

• std::bad_alloc in the event of a memory allocation failure.
• c8::invalid_argument in the event of an empty, or incorrectly formed, string v.

c8::rational::rational

rational(const rational &v);

Constructs a c8::rational by copying the existing rational v.

Exceptions

• std::bad_alloc in the event of a memory allocation failure.

c8::rational::rational

rational(rational &&v) noexcept;

Constructs a c8::rational by moving the contents of the existing rational v. Afterwards v will be left as zero.

Exceptions

None.
