double DesignGlassPric eDbl =WindowAreaSqFt Int * DesignGlassPric ePSF;
int DesignGlassPric eInt= System.ConvertT oInt32(DesignGl assPriceDbl);
In the above code, if "DesignGlassPri ceDbl" is 213.33, DesignGlassPric eInt
evaluates to 104, not 213.
How can I convert a double value to an Int? Dropping .33 in the process is
OK, but not dropping (for some reason inexplicable to me) 109.33. 4 47964
Worked fine for me (once I inserted a dot between Convert and ToInt32).
Framework 1.1 returned 213, as expected.
Apart from the obvious question (i.e., are you sure that DesignClassPric eDbl
actually equalled 213.33 in your test), what's different about your setup?

Could you post a short but complete program which demonstrates the
problem?
See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.
(I would also suggest just casting, rather than using Convert.ToInt32 ,
but that's a different matter.)

In my code prior to the first line show, I was mixing doubles and decimals,
so maybee "DesignGlassPri ceDbl" was not really a double.
Anyway, I ended the mixing by making all the variables doubles and now the
code works fine.
Appararently one should not mix variables like I did and not expect trouble?
Thanks for your offer!!

Well, it shouldn't make that kind of trouble at all - I'd still be
intrigued to see what produced those results. I'm glad it's all working
though :)

Why does this not work, and how should i do this convert in stead:

hi all.
In my program I need to convert a double number to stringrepresentation in fraction format and vise versa. For example,convert 0.75 to string "3/4" and convert string "1/2" to 0.5.The class will only need to handle numbers that increment by1/32. That is 1/32, 2/32, 3/32.... 31/32, 1. If the doublenumber is 0.28 which is between 1/4 and 9/32, the string shouldbe 9/32(go with the bigger number).
TIA

Hello -
I am reading up on the NumberFormatInfo 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%

I have tried to use FormatNumber() to convert a very large double type
number to String format, however, the result seems not correct, is there any
limitation for using FormatNumber() function?
For example, I write the code shown below:
Dim DblA as double = 999999999999999.12
Dim VarA As String = FormatNumber(DblA)
The result of VarA contains value "999999999999999.00" instead of
"999999999999999.12".

Except the ways following:

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
