如何在Javascript中为if语句添加容差

function areValuesEqualWithTolerance(value1, value2, tolerance) {
    return Math.abs(value1 - value2) <= tolerance;
}

// 示例使用
let a = 0.1 + 0.2;
let b = 0.3;
let tolerance = 0.0001;

if (areValuesEqualWithTolerance(a, b, tolerance)) {
    console.log("值在容差范围内相等");
} else {
    console.log("值不相等");
}

const _ = require('lodash');

function areValuesEqualWithTolerance(value1, value2, tolerance) {
    return _.isEqualWith(value1, value2, (v1, v2) => {
        if (_.isNumber(v1) && _.isNumber(v2)) {
            return Math.abs(v1 - v2) <= tolerance;
        }
    });
}

// 示例使用
let a = 0.1 + 0.2;
let b = 0.3;
let tolerance = 0.0001;

if (areValuesEqualWithTolerance(a, b, tolerance)) {
    console.log("值在容差范围内相等");
} else {
    console.log("值不相等");
}
