}Expand description
Methods for float random number generation that are common in GPU/massively parallel applications. Such as uniform or normal f32/64 generation.
Required Methods§
Sourcefn uniform_f32(&mut self) -> f32
fn uniform_f32(&mut self) -> f32
Creates an f32 in the range of [0.0, 1.0) and advances the state once.
Sourcefn uniform_f64(&mut self) -> f64
fn uniform_f64(&mut self) -> f64
Creates an f64 in the range of [0.0, 1.0) and advances the state once.
Sourcefn normal_f32(&mut self) -> f32
fn normal_f32(&mut self) -> f32
Creates an f32 with normal distribution. The value is drawn from a Gaussian of
mean=0 and sigma=1 using the Box-Mueller transform. Advances the state twice.
Sourcefn normal_f64(&mut self) -> f64
fn normal_f64(&mut self) -> f64
Creates an f64 with normal distribution. The value is drawn from a Gaussian of
mean=0 and sigma=1 using the Box-Mueller transform. Advances the state twice.
Sourcefn normal_f32_2(&mut self) -> [f32; 2]
fn normal_f32_2(&mut self) -> [f32; 2]
Same as Self::normal_f32 but doesn’t discard the second normal value.
Sourcefn normal_f64_2(&mut self) -> [f64; 2]
fn normal_f64_2(&mut self) -> [f64; 2]
Same as Self::normal_f64 but doesn’t discard the second normal value.
