(PECL spl_types >= 0.1.0)
SplFloat::__construct — Constructs a float object type
This constructs a new object of type float.
没有返回值。
Example #1 SplFloat::__construct() example
<?php
$float = new SplFloat(3.154);
$newFloat = new SplFloat(3);
try {
$float = 'Try to cast a string value for fun';
} catch (UnexpectedValueException $uve) {
echo $uve->getMessage() . PHP_EOL;
}
var_dump($float);
var_dump($newFloat);
?>
以上例程会输出:
Value not a float object(SplFloat)#1 (1) { ["__default"]=> float(3.154) } object(SplFloat)#2 (1) { ["__default"]=> float(3) }
