class Intl.NumberFormat { +format(number) +resolvedOptions() -locale -options } 在这里,Intl.NumberFormat类负责处理数字格式化;它的format方法用于输出格式化以后的数字。 数学公式 数字格式化过程中的计算可以用以下公式描述: [ \text{输出} = \text{groupDigits}(\text{数字}) \ \text{输出} = \text{form...
Integers (numbers without a period or exponent notation) are accurate up to 15 digits. Example letx =999999999999999;// x will be 999999999999999 lety =9999999999999999;// y will be 10000000000000000 Try it Yourself » The maximum number of decimals is 17. ...

但其实有更优雅的正则方式, 当我传入0进行格式化时, 只需要匹配出 "数字1 + 小数点 + 数字2" 的模式中的数字2的长度即可: let maxFractionDigits = 0; const currencyTempString = formatFn(0).replace(/\s/g, ""); const regVal = /[0〇]+[\.\,]([0〇]+)/g; ...
Number(parseFloat(3000).toFixed(2)).toLocaleString('en', { minimumFractionDigits: 2 }); // result 123,233.12 Number(parseFloat(123233.12).toFixed(2)).toLocaleString('en', { minimumFractionDigits: 2 }); Do comment if you have any doubts or suggestions on this JS number format topic. ...
问在JavaScript中使用恰好两个小数的数字格式化EN要使用定点表示法设置数字格式，只需使用toFixed方法：
functionformat_with_Intl(number, minimumFractionDigits, maximumFractionDigits) { minimumFractionDigits = minimumFractionDigits ||2; maximumFractionDigits = (maximumFractionDigits ||2); maximumFractionDigits =Math.max(minimumFractionDigits, maximumFractionDigits);returnnewIntl.NumberFormat('en-us', {maximum...
