我试图在价格结束时删除.00
function getMoney($mon) {
setlocale(LC_MONETARY, 'en_US');
return money_format('%.2n', $mon);
}
谢谢,
我使用spring currency formatter根据货币代码格式化值
public String format(Number number, String currencyCode)
{
CurrencyFormatter formatter = new CurrencyFormatter();
formatter.setCurrency(Currency.getInstance(currencyCode));
return formatter.print(number, Locale.getDefault());
}
因此,如果我将其称为格式(10,"GBP"),那么无论区域设置是什么,我都希望该值返回10.00英镑.
这可能吗？
我只想添加数字(货币,如果你愿意),像1.5和1.47一样,并使它等于1.97.
这是如何完成的？我不知道我不知道怎么做!:)
var discountAmount = 0;
var ogCookie = < %= strJsonCookie % >
for (var i = 0; i < ogCookie.products.length; i++) {
discountAmount = parseFloat(discountAmount) + parseFloat(ogCookie.products[i].discount_amount);
}
alert(discountAmount);
我试图编写一个算法来计算用给定面额制作一定数量的不同可能方式的数量.假设美元的面额分别为100美元,50美元,20美元,10美元,5美元,1美元,0.25美元,0.10美元,0.05美元和0.01美元.下面的函数,适用于int amount和int denominations
/* Count number of ways of making different combination */
int Count_Num_Ways(double amt, int numDenom, double S[]){
cout << amt << endl; //getchar();
/* combination leads to the amount */
if(amt == 0.00)
return 1;
/* No combination can lead to negative sum*/
if(amt < 0.00)
return 0;
/* All denominations have been exhausted and we have not reached
the required sum */
if(numDenom < 0 && amt >= 0.00)
return 0;
/* either we pick this …我正在考虑将numeric我的PG 9.2数据库模式的列转换为money,主要是因为我看到(或想象？)在数据库级别而不是应用程序级别处理舍入和格式化的好处.这个决定会有一些缺点吗？
例如,文本框中的输入字符串为10.00美元.我打电话
decimal result;
var a = decimal.TryParse(text, NumberStyles.AllowCurrencySymbol, cultureInfo, out result);
cultureInfo是已知的(en-US).为什么decimal.tryParse返回错误？
谢谢.
假设我有以下<f:convertNumber>格式来设置货币类型编号:
<f:convertNumber type="currency" locale="#{userSession.locale}" pattern="$###,###.###" />
在英语中,一百万将是1,000,000,但在德国,它应该是1.000.000.我的问题是:如果我使用上面的模式,JSF是否会知道指定语言环境的数字格式并自动使用正确的分隔符？
如果没有,如果您能告诉我如何格式化货币编号并同时指定正确的数字分隔符,我将非常感激.
我有这个货币清单(来自https://openexchangerates.org)

并知道我想为每种货币添加正确的货币符号和货币名称(使用本地语言).
有没有人知道这样的货币符号列表
$';€';£';我不确定,每种货币都存在"HTML编码(数字)"的标志吗？
(通常)是否可以将本机货币名称存储在普通的JS对象中？
提前致谢.
我从API获得以下JSON响应.
{
"status": "success",
"data": [
{
"actual_price": 30,
"offered_deal_price": 16,
"pending_balance": 12.8
}
]
}
所有这些价值都是价格.这意味着它们可以是圆值或浮点值.
我读过你应该使用NSDecimalNumbertype作为货币值.我在转换这些JSON值时遇到问题.
这样做,
json["pending_balance"] as! NSDecimalNumber
失败,出现以下错误.
无法将'__NSCFNumber'(0x10423ccf0)类型的值转换为'NSDecimalNumber'(0x1046cf1f0)
试图把它投射到NSDecimal这导致了这个
无法将类型'__NSCFNumber'(0x7f9102f79f68)的值转换为'C.NSDecimal'(0x10f23d6e0).
但是,我可以将它转换为Swift类型,Float无论Double是否有问题.
任何人都知道问题是NSDecimalNumber什么？或继续安全Float或Double？如果是这样哪一个最适合货币价值？
谢谢.
我无法将数字显示为货币.
我使用的代码是:
<h:outputText id="id_importo" value="33333,33">
<f:convertNumber type="currency" currencySymbol="€" locale="it_IT"/>
</h:outputText>
产生此错误:
