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);
}
