JavaScript Integer Accuracy JavaScript integers are only accurate up to 15 digits: Integer Precision letx =999999999999999; lety =9999999999999999; Try it Yourself » In JavaScript, all numbers are stored in a 64-bit floating-point format (IEEE 754 standard). ...

目前,JavaScript 语言中共有以下七中原始数据类型: Undefined Null Boolean String Symbol Number BigInt JavaScript 语言使用双精度 64 位浮点数格式来表示 Number 类型的值。Number 类型能够安全表示的最大整数为 2^53 - 1,该数值能够使用内置的 Number 对象上的 MAX_SAFE_INTEGER 属性来表示。BigInt 类型能够表示...
可以参考Number.isSafeInteger()的定义。 二、BigInt 类型 在ES2020 之前,JavaScript 只有一种数值类型:number(数字),而之后为了安全表达比-9007199254740991 ~ 9007199254740991安全范围之外的数字。引入了BigInt类型。 一般计算机是将整数存储在 CPU 的寄存器中(现在通常是 32 位或 64 位宽, JS 是 64bit),或者存储...

其中负数用补码表示。 --- 整数二进制求法： 十进制转成十六进制：Integer.toHexString(int i) 十...
Yet another class for arbitrary-precision integers in pure JavaScript. Small. Well tested.. Latest version: 3.0.26, last published: 8 months ago. Start using js-big-integer in your project by running `npm i js-big-integer`. There are 3 other projects in
// 假设某个库默认使用 BigInt let value = library.getValue(); if (typeof value === 'bigint' && value <= Number.MAX_SAFE_INTEGER) { value = Number(value); // 转换回普通数字 } 总结 不必要的 BigInt 转换通常源于对数据类型和应用场景理解不足。通过仔细检查数据需求、合理使用条件转换和优化...
