Detailed Description

This file implementes the interface of the Fraction class.

Private and protected members of the class are also implemented in this file.

Define Documentation

#define ACCLIMIT   100000000

Determines the accuracy when converting a decimal number into a fraction.

Currently, conversion is accurate to 3-4 decimal places.

Increase number to increase accuracy. However, if it becomes too large, conversion operation will fail due to how numbers are represented in memory in c++.

Function Documentation

bool operator!=	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if the two fraction objects aren't equal. False otherwise.

Definition at line 328 of file Fraction.cpp.

Fraction operator*	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction on the left of the operator
right	Fraction on the right of the operator

Returns:

Returns the reduced product of the two fractions.

Definition at line 370 of file Fraction.cpp.

Fraction operator+	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction on the left of the operator
right	Fraction on the right of the operator

Returns:

Returns the reduced sum of the two fractions.

Definition at line 358 of file Fraction.cpp.

Fraction operator-	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction on the left of the operator
right	Fraction on the right of the operator

Returns:

Returns the reduced difference of the two fractions.

Definition at line 364 of file Fraction.cpp.

Fraction operator/	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction on the left of the operator
right	Fraction on the right of the operator

Returns:

Returns the reduced quotient of the two fractions.

Definition at line 376 of file Fraction.cpp.

bool operator<	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if left fraction is less than right fraction. False otherwise.

Definition at line 334 of file Fraction.cpp.

ostream& operator<<	(	ostream &	out,
		const Fraction &	fraction
	)

Parameters:

out	output stream (operation assumes stream is already setup (ie. connected to file, screen etc.)
fraction	Fraction object to output.

Returns:

Returns reference to output stream so that for instance, cout << x << y is possible.

Definition at line 384 of file Fraction.cpp.

bool operator<=	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if left fraction is less than or equal to right fraction. False otherwise.

Definition at line 340 of file Fraction.cpp.

bool operator==	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if the two fraction objects are equal. False otherwise.

Definition at line 322 of file Fraction.cpp.

bool operator>	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if left fraction is greater than right fraction. False otherwise.

Definition at line 346 of file Fraction.cpp.

bool operator>=	(	const Fraction &	left,
		const Fraction &	right
	)

Parameters:

left	Fraction object to the left of the operator.
right	Fraction object to the right of the operator.

Returns:

Returns true if left fraction is greater than or equal to right fraction. False otherwise.

Definition at line 352 of file Fraction.cpp.

istream& operator>>	(	istream &	in,
		Fraction &	fraction
	)

Parameters:

in	input stream (operation assumes stream is already setup (ie. connected to file, screen etc.)
fraction	The input from stream is assigned to this fraction object.

Returns:

Returns reference to input stream so that for instance, cin >> x >> y is possible.
