在Asp.net(c#)中
float 类型怎么保留两位小数呀

[xiaohutushen]

float.ToString("f2");//即可
或者用Math.Round(3.343434,2);

[wpfonline]

要是在 sql 库中呢

[gsk99]

sql

round(xxxx,2)
xxxx是字段名

[gsk99]

SELECT ROUND(Sc1003, 2) AS Sc1003
FROM dbo.sc010

[huyanjiang]

aa= 1232.3435
select cast(aa as varchar) from table

[mingwj1980]

f.ToString("0.00")

[viena]

float f = 1234.12345f;
textBox3.Text=f.ToString("0.0#");

[antiking]

textBox3.Text=f.ToString("f");

[暗夜幽风]

float f=a.ToString("0.00")
