phi
Floats suck. So lets make an analogue fractional calculator. Join in!, (*1)
v0.0.5
Refactoring fractions (apparently) works! We might need more test cases. Help us add some!, (*2)
install the project
First fork the project on GitHub. Then,, (*3)
git clone https://github.com/your-github-name/phi
cd phi
composer install
run the tests
codecept run unit --coverage-html
Or you can log into https://travis-ci.org/ and hook up your forked repository.
Then by git pushing the tests will run., (*4)
do your thing
You either build, break, or fix. Get the test passing, or add a new set of data
which will make the tests fail., (*5)
new feature
We have a setNegative($bool) method for negative fractions. We haven't added any test cases
for that, so why not join in the fun? :-), (*6)
adding a test case
In tests/unit/Phi/PhiTest.php you can see the testToString() test. There is a dataset, each being
an array with four values; the whole, the numerator, the denominator, and the expected string output.
Contributing can be as simple as throwing some numbers in there and try to break the class!, (*7)
send your pull request
Because contributing to open source is fun!, (*8)
usage
Right now, there is only one class, Del\Phi\Fraction. An object representing a fraction, comprising
of a whole number, and fractional numerator and denominator., (*9)
<?php
use Del\Phi\Fraction;
$phi = new Fraction();
$phi->setWhole(3)
->setNumerator(3)
->setDenominator(4);
echo $phi->toDecimal(); // float 3.75
echo $phi; // string '3 3/4'
More functionality will be made soon, but first we need tests which will break the current logic
and give us unexpected output! (for example '3 3/3' should really output 4), (*10)
