The show of percentage sign is only for the UI presentation, there is no need to store it to database. In your case, set the date type of the database table column to decimal[^] with the appropriate precision and scale. Use Insert Into[^] to insert the value into the table.

Solution 1

first of all you need to change your code to get correct value with decimal places, for example

C#

float c =((float)a/b)*100;

otherwise you will get zero as result.
then read SQL Server Data Type Mappings[^] find the maping data type for the .net data type
