PHP gmp_invert()函数

PHP有一个叫做GMP invert()的函数，它在另一个GMP编号下查找一个GMP编号的模逆。

语法

下面的语法展示了PHP GMP反转函数。

参数

正如您在上面的语法中所看到的，这个函数接受两个GMP数字，$ numbers1和$ numbers2。
当$b除以$a时，这个函数的结果与$a相反。在PHP 5.6及更高版本中，这些参数可以是GMP对象。
我们也可以传递一个数字字符串，只要这个字符串变成一个数字。

返回值

这个函数返回一个GMP数，它是作为参数给出的两个数的逆模。
如果给定的两个数不能用于求逆模，该函数将返回FALSE。

例子

下面的例子展示了使用GMP函数的几个参数的模逆值。

例二:下面的示例展示了带有基本值的gmp_invert()函数。给定参数表示给定数的模逆值。
