Question

这是代码，但我如何应用舍入函数??

＆＃13;

var Currency = {

Answer 1

See this post about .toFixed()并注意它可能存在准确性问题。

var Currency = {
  rates: {"USD":1.0,"EUR":1.18122,"GBP":1.32077,"CAD":0.796995},
  convert: function(amount, from, to) {
    return ((amount * this.rates[from]) / this.rates[to]).toFixed(2);
  }
};

var val; //value to convert
var src; //convert from
var tgt; //convert to

val=12; src="USD"; tgt="GBP";
console.log('$' + val + ' ' + src + ' = $' + Currency.convert(12,src,tgt) + ' ' + tgt);

val=9.45; src="USD"; tgt="CAD";
console.log('$' + val + ' ' + src + ' = $' + Currency.convert(12,src,tgt) + ' ' + tgt);

为什么舍入转换的固化物在shopify中不起作用？
