nikisas_test

用于测试数学函数实现质量的工具。计算从给定区间随机采样的输入的错误。

使用方法

确定错误

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");

确保所需的误差界限

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()));
