This package is auto-updated.

Last update: 2024-10-24 12:54:49 UTC

README

Library containing value objects to represent numeric information, parsers to turn user input into such value objects, and formatters to turn them back into user consumable representations.

It is part of the DataValues set of libraries.

Installation

The recommended way to use this library is via Composer.

Composer

To add this package as a local, per-project dependency to your project, simply add a dependency on data-values/number to your project's composer.json file. Here is a minimal example of a composer.json file that just defines a dependency on version 0.8 of this package:

{
    "require": {
        "data-values/number": "0.12.*"
    }
}

Manual

Get the code of this package, either via git, or some other means. Also get all dependencies. You can find a list of the dependencies in the "require" section of the composer.json file. Then take care of autoloading the classes defined in the src directory.

Tests

This library comes with a set up PHPUnit tests that cover all non-trivial code. You can run these tests using the PHPUnit configuration file found in the root directory. The tests can also be run via TravisCI, as a TravisCI configuration file is also provided in the root directory.

Authors

DataValues Number was created by Wikimedia Deutschland employees for the Wikidata project.

Release notes

0.12.3 (2022-10-24)

  • Allow use with data-values/common 1.1.0 and data-values/interfaces 1.x

0.12.2 (2022-10-21)

  • Fix QuantityValue and UnboundedQuantityValue hashes to be identical to version 0.11.1.

0.12.1 (2022-10-21)

  • Allow use with data-values/data-values 3.1.0

0.12.0 (2022-10-21)

  • Improve compatibility with PHP 8.1; in particular, the new __serialize/__unserialize methods are implemented now (in addition to the still supported Serializable interface). Make sure to also use data-values/data-values version 3.1.0 (or later) to keep hashes stable.
  • Remove the DATAVALUES_NUMBER_VERSION constant.

0.11.1 (2021-03-31)

  • Fix DecimalMath::productWithoutBC for products larger than 2^63-1 (the maximum value of a signed 64 bit integer).

0.11.0 (2021-03-15)

  • Drop support for php versions older than 7.2 and HHVM

0.10.2 (2021-03-15)

  • Allow use with data-values/common 1.0.0
  • Allow use with data-values/interfaces 1.0.0
  • Allow use with data-values/data-values 3.0.0

0.10.1 (2018-10-31)

  • Allow installation together with DataValues 2.x
  • DecimalMath products now get rounded to 127 characters to avoid a fatal error

0.10.0 (2018-04-11)

  • Changed the float to string conversion algorithm for DecimalValue, QuantityValue, and UnboundedQuantityValue. Instead of a hundred mostly irrelevant decimal places it now uses PHP's "serialize_precision" default of 17 significant digits.
  • Drop compatibility with data-values/interfaces 0.1 and data-values/common 0.2

0.9.1 (2017-08-09)

  • Allow use with data-values/common 0.4

0.9.0 (2017-08-09)

  • Remove MediaWiki integration
  • Strip all whitespace in DecimalParser
  • Use Wikibase's CodeSniffer instead of MediaWiki's

0.8.3 (2017-06-26)

  • Fixed UnboundedQuantityValue::newFromArray not accepting mixed values.
  • Deprecated DecimalValue::newFromArray and UnboundedQuantityValue::newFromArray.
  • Updated minimal required PHP version from 5.3 to 5.5.9.

0.8.2 (2016-11-17)

  • Fixed QuantityFormatter suppressing ±0 for QuantityValues.
  • Fixed HTML escaping in QuantityHtmlFormatter.

0.8.1 (2016-08-02)

  • UnboundedQuantityValue::newFromArray and QuantityValue::newFromArray both accept serializations without and with an uncertainty interval.

0.8.0 (2016-08-01)

  • Added DecimalValue::getTrimmed.
  • Added UnboundedQuantityValue.
    • QuantityValue extends UnboundedQuantityValue.
    • QuantityParser returns UnboundedQuantityValues instead of always guessing an uncertainty interval.
    • QuantityFormatter also accepts UnboundedQuantityValues.
  • QuantityParser defaults to ±0.5 instead of ±1 when asked to guess an uncertainty interval, e.g. 1~ becomes 1±0.5.
  • QuantityFormatter does not round any more when the value is rendered with a known uncertainty interval.
  • Fixed rounding algorithm in DecimalMath (rounded 1.45 to 2 instead of 1).
  • DecimalValue constructor optionally accepts strings with no leading plus sign.
  • Removed QuantityValue::getSignificantFigures.
  • Removed QuantityValue::newFromDecimal (deprecated since 0.1).
  • The $vocabularyUriFormatter parameter in the QuantityFormatter constructor is not nullable any more.

0.7.0 (2016-04-25)

Breaking changes

  • Removed deprecated QuantityUnitFormatter interface.
  • Removed deprecated BasicQuantityUnitFormatter.

Other changes

  • Fixed DecimalValue and QuantityValue allowing values with a newline at the end.
  • DecimalValue strings are trimmed now, allowing any number of leading and trailing whitespace.
  • Added explicit compatibility with data-values/common 0.2 and 0.3.

0.6.0 (2015-09-09)
