如何在javascript中比较两个大数

Question

为什么下面的代码输出结果是相等的？如何比较？

var num1 = 340282000000000000000000000000000000001
var num2 = 340282000000000000000000000000000000000  // 3.402823E+38
if(num1 == num2) {
    console.log('num1 equal to num2');
} else if(num1 > num2) {
    console.log('num1 bigger than num2');
} else {
    console.log('num1 lower than num2')
}

Answer 1

尝试将它们定义为

BigInt

：

var num1 = 340282000000000000000000000000000000001n;
var num2 = 340282000000000000000000000000000000000n;
if(num1 == num2) {
    console.log('num1 equal to num2');
} else if(num1 > num2) {
    console.log('num1 bigger than num2');
} else {
    console.log('num1 lower than num2')
}
