如何在C＃中的double类型的条件下获取零值的十进制值

Question

Here below is the operations..

double d=4.0;
double dd=4.0;
double results=d+dd;

it gives at the time of execution

results => 8

Instead of

results => 8.0

I would like to get output like below

results => 8.0

Will anybody tell me how to get decimal value with zero's also

Answer 1

You can use String format for desired output. like

    String.Format(((Math.Round(results) == results) ? "{0:0}" : "{0:0.00}"), results);
