Well 12 and 12 00 have exactly the same representation as double values  Are you trying to end up with a double or something else   For example  you could cast to int  if you were convinced the value would be in the right range  and if the truncation effect is what you want    You might want to look at these methods too    Math Floor Math Ceiling Math Round  with variations for how to handle midpoints  Math Truncate

Reading all the comments by you  I think you are just trying to display it in a certain format rather than changing the value   casting it to int   I think the easiest way to display 12 00 as  12  would be using string format specifiers   double val   12 00   string displayed value   val ToString  N0       Output will be  12    The best part about this solution is  that it will change 1200 00 to  1 200   add a comma to it  which is very useful to display amount money price of something   More information can be found here  https   msdn microsoft com en-us library kfsatb94 v vs 110  aspx

If you just need the integer part of the double then use explicit cast to int    int number    int  a    You may use Convert ToInt32 Method  Double   but this will round the number to the nearest integer       value  rounded to the nearest 32-bit signed integer  If value is   halfway between two whole numbers  the even number is returned  that   is  4 5 is converted to 4  and 5 5 is converted to 6
