# Fraction
|
|
|
|
Arduino library to implement a Fraction datatype (experimental)
|
|
|
|
## Description
|
|
|
|
The fraction library implements fractional numbers a.k.a. Q,
|
|
(integers are Z and floats/doubles are R),
|
|
and the conversion to floats.
|
|
|
|
The code is working with a number of limitations among others:
|
|
- denominator is max 4 digits to keep code for multiply and divide simple
|
|
- Fractions are not exact (even floats are not exact)
|
|
- the range of numbers supported is limited.
|
|
- code is experimental still.
|
|
|
|
That said, the library is useful e.g. to display float numbers as a fraction.
|
|
From programming point of view the fractionize function, converting a double
|
|
into a fraction is a nice programming problem, fast with a minimal error.
|
|
|
|
In short, use fractions with care otherwise your sketch might get broken ;)

The library is reasonably tested, and if problems arise please let me know.
