FermatPHP 数据统计包
Fermat 是一个 PHP 开发包,可以对任意规模的数据进行数学和统计。
示例代码1:
<?php use Samsara\Fermat\Numbers; $five = Numbers::make(Numbers::IMMUTABLE, 5); $ten = Numbers::make(Numbers::IMMUTABLE, '10'); echo $five->add($ten); // Prints: "15"
示例代码2:
<?php use Samsara\Fermat\Values\ImmutableNumber; use Samsara\Fermat\Values\ImmutableFraction; $five = new ImmutableNumber(5); $oneQuarter = new ImmutableFraction(1, 4); echo $five->add($oneQuarter); // Prints: "5.25" // The asDecimal() method is called on $oneQuarter echo $oneQuarter->add($five); // Prints: "21/4" // Calls getValue() on $five and instantiates a new ImmutableFraction
