我正在尝试用 HTML Javascript 制作一个分数计算器，我需要简化分数，我该怎么做？

我的计算器的非脚本部分是这样的（包含所有输入）：分数计算器我的计算器的非脚本部分是这样的（包含所有输入）： <body> <p class="box">Fraction Calculator</p> <input type="number" id="n1"> <select id="operation"> <option value="1">X</option> <option value="2">/</option> <option value="3">+</option> <option value="4">-</option> </select> <input type="number" id="n2"> <br> <input type="number" id="n3"> <input type="number" id="n4" style="margin-left:37px"> <br> <button style="margin-left:130px"; onClick="document.getElementById('fraction').innerHTML = option()">Go!</button> <p id="fraction"></p> </body> 我的选项功能是这样的： function option() { selection = document.getElementById('operation').value; if(selection == "1"){ a = multiply(); return a } else if(selection == "2"){ b = division(); return b } else if(selection == "3"){ c = addition(); return c } else{ d = subtraction(); return d } } 所以我当前计算器乘法部分的代码是这样的： function multiply() { Number1 = parseInt(document.getElementById("n1").value); Number2 = parseInt(document.getElementById("n2").value); Number3 = parseInt(document.getElementById("n3").value); Number4 = parseInt(document.getElementById("n4").value); var topm = Number1 * Number2; var botm = Number3 * Number4; return topm + "/" + botm; } 所以目前我的计算器可以工作，但没有一个分数被简化。我怎样才能简化这些分数？（我对代码还算陌生）谢谢:) 这是 JSFiddle 链接：https://jsfiddle.net/Ethang70/npgL3gd9/ 为了简化分数，您要做的就是计算分母和分子之间的最大公约数，然后将两者除以 GCD。计算 GCD 的一种方法是使用欧几里得算法。 Javascript 中的一种实现可能是： function gcd(a,b) { if (b == 0) { return a; } else { return gcd(b, a % b); } } 此后，当您打印分数时，您可以执行以下操作： function multiply() { Number1 = parseInt(document.getElementById("n1").value); Number2 = parseInt(document.getElementById("n2").value); Number3 = parseInt(document.getElementById("n3").value); Number4 = parseInt(document.getElementById("n4").value); var topm = Number1 * Number2; var botm = Number3 * Number4; var divisor = gcd(topm, botm); topm = topm / divisor; botm = botm / divisor; return topm + "/" + botm; } 祝你好运！如果您愿意使用小型第三方脚本，您可以查看fraction.js。根据@Zyberzero的答案，它计算非整数的最大公约数并将其返回为它可以作为字符串生成的最低分数： var myNum = 0.5; var fraction = new Fraction(myNum); console.log(fraction.toString()); // Returns 1/2 如果结果是整数，则返回相同的整数。如果结果包含整数，则会以int d/n格式返回；所以如果你只想要分数，你可以在空间周围分开。但这取决于你想降到多低；有一些小数值名义上代表分数，但不能除以您可能想要的“最低”分数。例如，0.3333333333...表面上代表三分之一，但fractions.js会（正确地）返回33/100。在我最近的用例中，我想要特别低的分数，如 1/3、1/9、2/3 等（基于小数值，如 0.33、0.11、0.66），所以我写了一个快速的& 肮脏的 if/else 给我我想要的较低分数： var fractionString = fraction.toString(); var singleQuantity = ''; if (fractionString.indexOf(' ') > 0) { var quantitySplit = fractionString.split(' '); var fractionSplit = quantitySplit[1].split('/'); singleQuantity = quantitySplit[0] + ' '; topFraction = parseInt(fractionSplit[0]); bottomFraction = parseInt(fractionSplit[1]); } if (bottomFraction == 100) { switch (topFraction) { case 11 : { topFraction = 1; bottomFraction = 9; break; } case 33 : { topFraction = 1; bottomFraction = 3; break; } } } if (bottomFraction == 50) { switch (topFraction) { case 33 : { topFraction = 2; bottomFraction = 3; break; } } } 这非常准确： <script> // Simple Fraction Calculator function calculateSimpleFraction() { const numerator1 = parseInt(document.getElementById('numerator1-simple').value) || 0; const denominator1 = parseInt(document.getElementById('denominator1-simple').value); const numerator2 = parseInt(document.getElementById('numerator2-simple').value) || 0; const denominator2 = parseInt(document.getElementById('denominator2-simple').value);
