A
fraction
is a number that is written as follows : `a/b` with a and b integers and b not zero. It's the quotient of a by b,
that is to say : `a/b` = a:b.
a is the
numerator
of the fraction and b is the **denominator of the fraction**. In other words, in a fraction, the numerator term is
located above the stroke, the **denominator** is the end located below the stroke.
The calculator with the denominator function used to **find the denominator of a fraction** or an expression with fractions.

The calculator is able to **determine the denominator** of a fraction : to find the fraction denominator of
`4/5`, enter
denominator(4/5),
after calculus, the result `5` is returned.

The calculator also applies to fractions that contain letters : to pour **calculate the fraction denominator**
of `a/b`, enter denominator(a/b) ,
after calculation, the result `b` is returned.

The denominator function is used on fractions but also to expressions containing fractions, after calculation, the simplified result is returned.

When the denominator function is applied to an algebraic expression, the expression is first converted to a fraction,
then the **denominator of the fraction** obtained is returned. So to find the denominator of the following expression
`4/5+3/7`, enter
denominator(4/5+3/7),
after calculation, he fraction obtained is `43/35`, then the function returns the denominator `35`.

The denominator function also applies to literal expressions.

The denominator function allows the calculation of the denominator of a fraction.

- denominator(4/5+3/7), returns 35
- denominator(0.5), returns 2
