Question

 var amount="0";
 @String.Format("{0:0.00}", amount)

returns "0"

While I was expecting it to return

"0.00"

Answer 1

Formatting a string will just return the string itself, you have to format a number to get it formatted as a number:

var amount = 0;

---

A variable with implicit type which is assigned an integer value will be an integer, so it won’t have a fractional part. You might want to specify the type:

double amount = 0;

Or use a double value:

var amount = 0.0;
