我想在php中将浮点值(例如:1.0000124668092E+14)转换为整数,php.output中最好的方法是100001246680920"
I want to convert float value (Eg:1.0000124668092E+14) to Integer in php,what is the best method for this in php.output should be "100001246680920"
转化是什么意思?
(int) $float
或 intval($float)
floor($float)
(向下)或 ceil($float)
(向上)round($float)
- 有额外的模式,请参阅 PHP_ROUND_HALF_...
常量(int) $float
or intval($float)
floor($float)
(down) or ceil($float)
(up)round($float)
- has additional modes, see PHP_ROUND_HALF_...
constants*:强制转换有一些机会,浮点值不能用 int 表示(太大或太小),f.ex.在你的情况下.
*: casting has some chance, that float values cannot be represented in int (too big, or too small), f.ex. in your case.
PHP_INT_MAX
:此 PHP 版本支持的最大整数.通常是 int(2147483647).
PHP_INT_MAX
: The largest integer supported in this build of PHP. Usually int(2147483647).
但是,您可以使用 BCMath 或 GMP 用于处理这些大数字的扩展.(两者都是有限制的,你只需要开启这些扩展)
But, you could use the BCMath, or the GMP extensions for handling these large numbers. (Both are boundled, you only need to enable these extensions)
