Function Documentation

bool operator!= ( number  a, number  b  )

inline

Compare two number objects for numeric inequality. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a != b (watch out for floating-point comparisons).

Definition at line 149 of file number.hpp.

{
  return not (a == b);
}

number operator- ( number  n )

inline

Negate a number.

Parameters

n	the number

Returns

-n

Definition at line 202 of file number.hpp.

{
  return number{0} - n;
}

bool operator< ( number  a, number  b  )

inline

Compare two number objects for numeric less-than. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a < b (watch out for floating-point comparisons).

Definition at line 160 of file number.hpp.

References number::less().

{
  return a.less(b);
}

std::ostream& operator<< ( std::ostream &  stream, number  n  )

inline

Print a number

Parameters

stream	The output stream
n	The number to print

Definition at line 211 of file number.hpp.

References number::print().

{
  n.print(stream);
  return stream;
}

bool operator<= ( number  a, number  b  )

inline

Compare two number objects for numeric less-than-or-equal. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a <= b (watch out for floating-point comparisons).

Definition at line 171 of file number.hpp.

{
  return not(b < a);
}

bool operator== ( number  a, number  b  )

inline

Compare two number objects for numeric equality. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a == b (watch out for floating-point comparisons).

Definition at line 138 of file number.hpp.

References number::equals().

{
  return a.equals(b);
}

bool operator> ( number  a, number  b  )

inline

Compare two number objects for numeric greater-than. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a > b (watch out for floating-point comparisons).

Definition at line 182 of file number.hpp.

{
  return b < a;
}

bool operator>= ( number  a, number  b  )

inline

Compare two number objects for numeric greater-than-or-equal. The objects are coerced to a common type before comparing.

Parameters

a	The left-hand operand
b	The right-hand operand

Returns

true if a >= b (watch out for floating-point comparisons).

Definition at line 193 of file number.hpp.

{
  return not (a < b);
