我有一个要显示的价格字段,有时可以是 100 或 100.99 或 100.9,我想要的是仅在为该价格输入小数位时以 2 位小数显示价格,例如,如果它是 100它应该只显示 100 而不是 100.00,如果价格是 100.2,它应该同样显示 100.20,因为 100.22 应该是一样的.我用谷歌搜索并发现了一些示例,但它们与我想要的不完全匹配:
I have got a price field to display which sometimes can be either 100 or 100.99 or 100.9, What I want is to display the price in 2 decimal places only if the decimals are entered for that price , for instance if its 100 so it should only show 100 not 100.00 and if the price is 100.2 it should display 100.20 similarly for 100.22 should be same . I googled and came across some examples but they didn't match exactly what i wanted :
// just two decimal places String.Format("{0:0.00}", 123.4567); // "123.46" String.Format("{0:0.00}", 123.4); // "123.40" String.Format("{0:0.00}", 123.0); // "123.00" 推荐答案不雅的方式是:
var my = DoFormat(123.0);DoFormat 类似于:
public static string DoFormat( double myNumber ) { var s = string.Format("{0:0.00}", myNumber); if ( s.EndsWith("00") ) { return ((int)myNumber).ToString(); } else { return s; } }不优雅,但在某些项目的类似情况下对我有用.
Not elegant but working for me in similar situations in some projects.
