How to: Convert DOUBLE to PERCENT?

[charliewest]

Hello -

I am reading up on the NumberFormatInf o class, trying to figure out how to
convert a double to a percentage, using the IFormatProvider . This seems a
little beyond me. Can anyone suggest an easy way to convert a double to a
percentage in C#?

For example, i would like to render on my web page the following:
..89 = 89%
1 = 100%

Thanks,

[Kevin Spencer]

Offhand, I'd guess that multiplying the double by 100 would give you the
percent value.

double dblTest = 0.89;
string strTest = dblTest.ToStrin g("0%");

1.
Use custom number formatting :
Pass your double to {0:0%}

2.
Format the double with the PercentDecimalD igits property.

Double myInt = 0.1234;
Console.WriteLi ne( myInt.ToString( "P", nfi ) );

will return 12.34 %

Thanks Kevin,

What i am trying to learn, however, is how to do this using the
NumberFormatInf o class, and/or IFormatProvider interface. This documentation
unfortunately, is not for newbies. Any examples, would be appreciated.

Thanks again,
