show decimal or double with zeros

Question

hi

i get price values from DB.

now whenever the price is perhaps 5, I want to show 5.00

if its 4.3 it should be 4.30.

how to convert that?

thanks

Answer 1

You can use the string format for decimal to apply this formatting.

YourDecimal.ToString("#,##0.00");

this should show 5.00, and 4.30.

Also it will show 1,234.56 groupings.

Answer 2

What data types do you use to store the price? It's a bad idea to store prices using floating point numbers because of precision issues. A fixed point number like a decimal is a better idea.

Once you're settled on a data type, you can use string formatting to display it correctly. See MSDN.

Answer 3

I never wrote a single line in Asp.net but simple search in google gave me this :

Answer 4

yourDecimal.ToString("N2") will also do the same
