示例 #1 BcMath\Number::ceil() example
<?php
$num1 = new BcMath\Number('4.3')->ceil();
$num2 = new BcMath\Number('9.999')->ceil();
$num3 = new BcMath\Number('-3.14')->ceil();
var_dump($num1, $num2, $num3);
?>以上示例会输出：
object(BcMath\Number)#2 (2) {
["value"]=>
string(1) "5"
["scale"]=>
int(0)
}
object(BcMath\Number)#3 (2) {
["value"]=>
string(2) "10"
["scale"]=>
int(0)
}
object(BcMath\Number)#4 (2) {
["value"]=>
string(2) "-3"
["scale"]=>
int(0)
}
