phpserver side programmingprogramming
要在 PHP 中比较浮点值,代码如下 −
示例
<?php $a = 2.5; $b = 3.5; echo $a; echo "
$b"; if($a == $b) { echo "
Both the values are equal!"; } else { echo "
Both the values aren\'t equal"; } ?>
输出
这将产生以下输出−
2.5 3.5 Both the values aren\'t equal
示例
现在让我们看另一个例子 −
<?php $a = 1.967; $b = 1.969; echo $a; echo "
$b"; if((round($a, 2)) == (round($b, 2))) { echo "
Both the values are equal!"; } else { echo "
Both the values aren\'t equal"; } ?>
输出
这将产生以下示例−
1.967 1.969 Both the values are equal!
