Function smartnoise_runtime::utilities::noise::sample_gaussian

pub fn sample_gaussian(
    shift: f64, 
    scale: f64, 
    _enforce_constant_time: bool
) -> Result<f64>

Generates a draw from a Gaussian(loc, scale) distribution using the MPFR library.

If shift = 0 and scale = 1, sampling is done in a way that respects exact rounding. Otherwise, the return will be the result of a composition of two operations that respect exact rounding (though the result will not necessarily).

Arguments

• shift - The expectation of the Gaussian distribution.
• scale - The scaling parameter (standard deviation) of the Gaussian distribution.

Return

Draw from Gaussian(loc, scale)

Example

use smartnoise_runtime::utilities::noise::sample_gaussian;
let gaussian = sample_gaussian(0.0, 1.0, false);
