Lcg_value() returns a pseudo random number in the range of (0, 1). lcg_value()返回范围为(0,1)的一个伪随机数。
Pseudo random sequence has broad applications in stream cipher, channel coding, and spread spectrum communication. 伪随机序列在流密码、信道编码、频通信等领域有着广泛的应用.
The discrete random numbers is generated from a continuous pseudo random variable scaled by rng, mean shifted by vsh and dicretized by step size drv. 离散随机数值取自一连续随机变数乘以缩放比、并以等阶梯大小离散化及平均值位移而得。
