nikisas_test
Utilities for testing implementation quality of mathematical functions. Computing errors for inputs randomly sampled from given interval.
Usage
To determine the errors:
use nikisas_test::prelude::*;
fn exp(x: f32) -> f32 {
// your implementation
# 0.0
}
// Uniformly sample 100000 values from -87.3 to 88.7.
UniformSample::with_count(-87.3, 88.7, 100000)
// Use implementation from the standard library as ground truth.
.error(|x| (exp(x), x.exp()))
// Print the errors to standard output.
.print_plain("exp");
To ensure desired error bounds:
use nikisas_test::prelude::*;
// Uniformly sample 100000 values from -87.3 to 88.7.
UniformSample::with_count(-87.3, 88.7, 100000)
// Use implementation from the standard library as ground truth.
// If eny specified error bound is violated, the program panics with a readable message.
.assert(ErrorBounds::new().rel(0.001).abs(0.0001), |x| (exp(x), x.exp()));
