PHP中比较浮点值
为了比较PHP中的float值，代码如下-
示例
<?php
$a = 2.5;
$b = 3.5;
echo $a;
echo "\n$b";
if($a == $b) {
echo "\nBoth the values are equal!";
} else {
echo "\nBoth the values aren\'t equal";
}
?>输出结果
2.5 3.5 Both the values aren\'t equal
示例
现在让我们来看另一个示例-
<?php
$a = 1.967;
$b = 1.969;
echo $a;
echo "\n$b";
if((round($a, 2)) == (round($b, 2))) {
echo "\nBoth the values are equal!";
} else {
echo "\nBoth the values aren\'t equal";
}
?>输出结果
这将产生以下示例-
1.967 1.969 Both the values are equal!
