I would like to know what exactly to use in my following code:


float v_tax = Convert.ToInt32(ds.Tables[0].Rows[i]["tax"]);


The 'tax' is a float datatype holding 12.55 as data.
During run time the variable v_tax is having value as 13 instead of 12.55.

Can anyone please guide me.
Regards.

"value as 13 instead of 12.55" that is because you are converting the value to an integer, "Convert.ToInt32"

Hi,

Use the Convert.ToSingle method[^] instead of the Convert.ToInt32 method:
float v_tax = Convert.ToSingle(ds.Tables[0].Rows[i]["tax"]);

Precision is the main difference between double and float. Decimal has more precision that float.
Try using float.
