在货币和时间上添加末位零
原标题:Add trailing zeros in money and time

我想知道如何在时间和现金上 加上末端零

我有这个:

01 h1 0.0美元

但我想得到它这样:

0010.00美元

最佳回答

对于货币,请使用 number_to_odalation 。它应该是类似的东西。

数字_to_to_货币(1.4, 格式: "%n% u")

时间,请使用strftime

问题回答

你在这里想要的是:

 %.2f  % your_thing

铁路中有一些帮助数字的方法。 请查看 < a href=" http:// appi. rubyonrails. org/ classes/ ActionView/ Helpers/Nuotelfelfer.html" rel=“ no follow” > http://api. rubyonrails. org/ classes/ ActionView/ Helpers/NotlePelfer. html (尤其是数字_ with_ pecision 可能对您的情况有意思)
