Function Documentation

init()

void rack::random::init

(

)

Initializes the thread-local RNG state.

Must call per-thread, otherwise the RNG will always return 0.

u32()

uint32_t rack::random::u32

(

)

Returns a uniform random uint32_t from 0 to UINT32_MAX.

u64()

uint64_t rack::random::u64

(

)

Returns a uniform random uint64_t from 0 to UINT64_MAX.

uniform()

float rack::random::uniform

(

)

Returns a uniform random float in the interval [0.0, 1.0)

normal()

float rack::random::normal

(

)

Returns a normal random number with mean 0 and standard deviation 1.
