Format decimal as a percent with specific decimal places

问题

<%= Model.STPData.InitialRateSetting.HasValue ? Model.STPData.InitialRateSetting.Value.ToString() : "" %>

The Model.STPData.InitialRateSetting is a decimal. I want to format that as a percentage, and then round it to 5 decimal places. How would I do that?

回答1:

you can use

Model.STPData.InitialRateSetting.Value.ToString("P5");

assuming InitialRateSetting is a decimal

回答2:

You could use ToString("p5"). This will take the number 0.051234567 and display it as "5.12346%". I'm not sure if it'll round that last place, to make sure the behavior or lack thereof is what you want.
