BLRandom Struct Reference
Simple pseudo random number generator based on XORSHIFT+, which has 64-bit seed, 128 bits of state, and full period 2^128 - 1.
Based on a paper by Sebastiano Vigna: http://vigna.di.unimi.it/ftp/papers/xorshiftplus.pdf

BLResult BLRandom::reset(uint64_t seed = 0)noexcept[¶]
Resets the random number generator to the given seed.
Always returns BL_SUCCESS.
bool BLRandom::equals(const BLRandom& other) constnoexcept[¶]
Tests whether the random number generator is equivalent to other.
- Note
- It would return true only when its internal state matches
other's internal state.
uint64_t BLRandom::nextUInt64()noexcept[¶]
Returns the next pseudo-random uint64_t value and advances PRNG state.
uint32_t BLRandom::nextUInt32()noexcept[¶]
Returns the next pseudo-random uint32_t value and advances PRNG state.
double BLRandom::nextDouble()noexcept[¶]
Returns the next pseudo-random double precision floating point in [0..1) range and advances PRNG state.
uint64_t BLRandom::data[2][¶]
PRNG state.
