MythRandom() [1/2]

uint32_t MythRandomStd::MythRandom ( )

inline

generate 32 random bits

Definition at line 20 of file mythrandom.h.

Referenced by rand_bool().

MythRandom64()

uint64_t MythRandomStd::MythRandom64 ( )

inline

generate 64 random bits

Definition at line 31 of file mythrandom.h.

MythRandom() [2/2]

uint32_t MythRandomStd::MythRandom ( uint32_t  min, uint32_t  max  )

inline

generate a uniformly distributed random uint32_t in the closed interval [min, max].

The behavior is undefined if .

An alternate name would be MythRandomU32.

Definition at line 45 of file mythrandom.h.

MythRandomInt()

int MythRandomStd::MythRandomInt ( int  min, int  max  )

inline

generate a uniformly distributed random signed int in the closed interval [min, max].

The behavior is undefined if .

Definition at line 58 of file mythrandom.h.

rand_bool()

bool MythRandomStd::rand_bool ( uint32_t  chance = 2 )

inline

return a random bool with P(true) = 1/chance

An input less than 2 always returns true:

• for chance = 1: range is [0, 0], i.e. always 0
• for chance = 0: range is [0, -1], unsigned integer underflow! (or just undefined behavior if signed)

This is a Bernoulli distribution with .
