## Fraction Calculators

This site is dedicated Fraction Calculator software.

Fraction Calculators are just like any other calculator except they
perform arithmetic operations on fractions instead of decimal numbers.
All four aritmetic operations are permited in fraction calculators and
the typical rules related to fractions still apply.

Since fraction calculators perform arithmetically on fractions, only
rational numbers are permited. Therefore, as you might have guessed,
there is no calculation using PI, square roots and there is no decimal
point key. Because whole numbers are rational numbers (their denominator is
the number "1"), fraction calculators can perform operations on whole numbers.
Since the "/" is taken for separation between the numerator
and denominator, another key expression must be used
to represent the division operator. For the current rendition, the key that
is responsible for division is printed with the words "Div".

Typically, calculators are divided into two categories: **Reverse Polish
Notation (RPN)**
and **Algebraic Notation**
(or **
infix notation**). These different types of calculators are simply
an indicator of how the arithmetic operator (+,-, * /) is noted in relation
to the operands. Typically,
Hewlett Packard is given credit for using RPN in calculators.
Most other calculator manufacturers use infix notation--even HP is now
releasing some of their calculators in infix notation. There are
benefits and drawbacks to both types of notations.

### RPN Fraction Calculators

This is an RPN Version of the Fraction Calculator software (as the name
would imply). This calculator works like all other
RPN calculators except
that it operates on fractions. Besides operating on fractions, the only
difference between this and other hardware oriented RPN calculators is
the stack is not size limited--rather only limited by the size of the memory.
In other words, this RPN fraction calculator has unlimited stack size.
