◆ to_lcg()

static void to_lcg ( const uint64_t *  ranlux,
unsigned  c,
uint64_t *  lcg 
)
static

Convert RANLUX numbers to an LCG state.

Parameters
[in]ranluxthe RANLUX numbers as 576 bits
[out]lcgthe 576 bits of the LCG state, smaller than m
[in]cthe carry bit of the RANLUX state

\( m = 2^{576} - 2^{240} + 1 \)
