包简介

A PHP library for working with precise numbers.

README 文档

README

A PHP library to convenient work with arbitrary precision numbers.

Requirements

PHP 8.1 or higher

Library is based on Brick\Math package:

Although the library can work seamlessly on any PHP installation, it is highly recommended that you install the GMP or BCMath extension to speed up calculations. The fastest available calculator implementation will be automatically selected at runtime.

Installation

You can install the package via composer:

composer require 021/numeric

Usage

use function O21\Numeric\Helpers\num;

$number = num('123.456');

echo $number->add('0.544')->get();

Calculations

All computational functions accept as an argument a value of one of the following types: string, float, int, \O21\Numeric\Numeric, \Brick\Math\BigNumber.

Function	Description
`add`	Adds a value to a number
`sub`	Subtracts a value from a number
`mul`	Multiplies a number by a value
`div`	Divides a number by a value

Comparisons

All comparison functions accept as an argument a value of one of the following types: string, float, int, \O21\Numeric\Numeric, \Brick\Math\BigNumber.

Function	Description
`equals`	Checks if two values are equal. It returns true if the values are equal and false otherwise.
`greaterThan`	Compares two values and returns true if the first value is greater than the second one.
`lessThan`	Compares two values and returns true if the first value is less than the second one.
`greaterThanOrEqual`	Compares two values and returns true if the first value is greater than or equal to the second one.
`lessThanOrEqual`	Compares two values and returns true if the first value is less than or equal to the second one.

Formatting

Function	Description
`positive`	Returns a number represented as positive.
`negative`	Returns a number represented as negative.
`scale`	Converts a number to a given scale, using rounding if necessary.
`get`	Returns a number as string. By default removes trailing zeros. Use the `raw: true` option to disable this.
`__toString`	Returns a `get` function result

Helpers

Namespace: O21\Numeric\Helpers

Function	Description
`num`	Creates a new `Numeric` instance
`num_min`	Returns a minimum value from a given values. Support any of these types: `string`, `float`, `int`, `\O21\Numeric\Numeric`, `\Brick\Math\BigNumber`
`num_max`	Returns a maximum value from a given values. Support any of these types: `string`, `float`, `int`, `\O21\Numeric\Numeric`, `\Brick\Math\BigNumber`
`to_bn`	Converts any of these types `string`, `float`, `int`, `\O21\Numeric\Numeric`, `\Brick\Math\BigNumber` to `\Brick\Math\BigNumber`
