Java BigInteger中的oddModPow java大数类的模幂计算中,其中比较核心部分就是使用一种窗口算法来优化乘法,然后使用Montgomery取模乘的办法加速取模。 在jdk中,它的源码如下: View Code 首先需要介绍一下它对于指数运算的手段: View Code 这段话的意思是,对于n^exp这个幂运算,在把exp转成二进制后,从高位开始向低位...

本文整理了Java中java.math.BigInteger.modPow()方法的一些代码示例,展示了BigInteger.modPow()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。BigInteger.modPow()方法的具体详情如下:包路径:java.math.BigInteger类名称...
It's possible that the modPow method allocates further objects during each call (you can check by looking at its source code - it's written entirely in Java). It does. The class uses MutableBigIntegers internally to do large calculations, and these need to be copied from the original ...
