Lehmer Random Number Generator - Sample C99 Code

Sample C99 Code

Using C code, the Lehmer generator using the "popular pair" of parameters mentioned above can be written as follows:

uint32_t lcg_rand(uint32_t a) { return ((uint64_t)a * 279470273UL) % 4294967291UL; }

As the product of two 32 bit integers may overflow, the cast to uint64_t is necessary.

Famous quotes containing the words sample and/or code:

    “All that a city will ever allow you is an angle on it—an oblique, indirect sample of what it contains, or what passes through it; a point of view.”
    —Peter Conrad (b. 1948)

    “...I had grown up in a world that was dominated by immature age. Not by vigorous immaturity, but by immaturity that was old and tired and prudent, that loved ritual and rubric, and was utterly wanting in curiosity about the new and the strange. Its era has passed away, and the world it made has crumbled around us. Its finest creation, a code of manners, has been ridiculed and discarded.”
    —Ellen Glasgow (1873–1945)
