Download the PHP package elliotjreed/maths without Composer

On this page you can find all versions of the php package elliotjreed/maths. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.
Please rate this library. Is it a good library?

Informations about the package maths

Maths

This PHP package provides an object-oriented wrapper for bcmath functionality and other common operations for dealing with numbers.

One aim of this project is to provide a greater degree of accuracy when dealing with floating point numbers.

Installation

To install the package via Composer, run:

or include the dependency in your composer.json file, for example:

Usage

There are two base classes, Number and NumberImmutable.

Both can take any numeric value in the constructor (i.e. a numeric string such as '1.5', an integer such as 150, a float such as 1.33, or a scientific notation string such as '8.431e-05').

The result can be returned as a string, integer, or float.

For an example of the differences between Number and NumberImmutable:

Number

The Number object is mutable.

Examples:

Numbers can be int, float, string, or instances of Number.

NumberImmutable

The NumberImmutable class is immutable.

Examples:

Numbers can be int, float, string, or instances of Number.

Development

Getting Started

PHP 8.1 or above and Composer is expected to be installed.

Installing Composer

For instructions on how to install Composer visit getcomposer.org.

Installing

After cloning this repository, change into the newly created directory and run:

or if you have installed Composer locally in your current directory:

This will install all dependencies needed for the project.

Henceforth, the rest of this README will assume composer is installed globally (ie. if you are using composer.phar you will need to use composer.phar instead of composer in your terminal / command-line).

Running the Tests

Unit tests

Unit testing in this project is via PHPUnit.

All unit tests can be run by executing:

Debugging

To have PHPUnit stop and report on the first failing test encountered, run:

Code formatting

A standard for code style can be important when working in teams, as it means that less time is spent by developers processing what they are reading (as everything will be consistent).

Code formatting is automated via PHP-CS-Fixer. PHP-CS-Fixer will not format line lengths which do form part of the PSR-2 coding standards so these will product warnings when checked by PHP Code Sniffer.

These can be run by executing:

Running everything

All of the tests can be run by executing:

Outdated dependencies

Checking for outdated Composer dependencies can be performed by executing:

Validating Composer configuration

Checking that the composer.json is valid can be performed by executing:

Running via GNU Make

If GNU Make is installed, you can replace the above composer command prefixes with make.

All of the tests can be run by executing:

Running the tests on a Continuous Integration platform (eg. Github Actions)

Specific output formats better suited to CI platforms are included as Composer scripts.

To output unit test coverage in text and Clover XML format (which can be used for services such as Coveralls):

To output PHP-CS-Fixer (dry run) and PHPCS results in checkstyle format (which GitHub Actions will use to output a readable format):

Github Actions

Look at the example in .github/workflows/main.yml.
