问题描述
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"
推荐答案
转化是什么意思?
- casting*:
(int) $float或intval($float) - 截断:
floor($float)(向下)或ceil($float)(向上) - 舍入:
round($float)- 有额外的模式，请参阅PHP_ROUND_HALF_...常量
- casting*:
(int) $floatorintval($float) - truncating:
floor($float)(down) orceil($float)(up) - rounding:
round($float)- has additional modes, seePHP_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)
