我们已经将输入的数字转换为字符串,现在可以使用 TypeScript 的内置函数BigInt()来将字符串转换为 BigInt 类型。下面是一个示例代码: functionconvertToBigInt(input:string):bigint{returnBigInt(input);} 1. 2. 3. 这个函数接受一个 string 类型的参数input,并返回一个 bigint 类型的结果。
转载:Typescript: how to convert number to an int8, int16, int32, uint8, uint16, or uint32 export class CONVERT { static NumberToUint32(x:number):number {returnx >>> 0; } static NumberToUint16(x:number):number {returnthis.NumberToUint32(x) & 0xFFFF; ...
然后,使用TypeScript的内置函数BigInt()将该字符串转换为BigInt类型。例如,const bigInt = BigInt(bigDecimal.toFixed())。 以下是一个完整的示例代码: 代码语言:txt 复制 import Big from 'big.js'; function convertBigDecimalToBigInt(bigDecimal: string): bigint { const bigDecimalObj = new Big(...

let myName: string = "Alice";Try TypeScript doesn’t use “types on the left”-style declarations like int x = 0; Type annotations will always go after the thing being typed. In most cases, though, this isn’t needed. Wherever possible, TypeScript tries to automatically infer the types...
比如如果我们将上边示例中的 convertToUpperCase 函数使用 TypeScript 实现，那么就需要显示地标明 strOrArray 的类型就是 string 和 string[] 类型组成的联合类型，如下代码所示：{ const convertToUpperCase = (strOrArray: string | string[]) => { if (typeof strOrArray === 'string') { return strOr...
