javascript将货币与数字相乘

// 假设我们有一个货币字符串和一个数字
const currencyString = "¥123.45";
const multiplier = 2;

// 移除货币符号并转换为数字
const currencyNumber = parseFloat(currencyString.replace(/[^\d.-]/g, ""));

// 进行乘法运算
const result = currencyNumber * multiplier;

console.log(result); // 输出: 246.9

const currencyString = "¥123,456.78";
const cleanCurrencyString = currencyString.replace(/[^\d.-]/g, "");
const currencyNumber = parseFloat(cleanCurrencyString);
console.log(currencyNumber); // 输出: 123456.78

const Decimal = require('decimal.js');

const currencyNumber = new Decimal('123.45');
const multiplier = new Decimal(2);
const result = currencyNumber.times(multiplier);

console.log(result.toString()); // 输出: "246.90"
