Is there a good reason that Decimal does not have Ceiling() method, only
Math class has?
Thanks!

Ryan,
AFAIK its in the maths class because it is a mathematical function. The
built in ceiling function dosn't actually work with decimal types only
double such as
double MyNumber = 1000.1;
MyNumber = Math.Ceiling(My Number);
Hope this helps

Math.Ceiling(de cimal) arrived in .NET 2.0.
As for why it's a static method - it does mean that if you want to take
a ceiling of a float, you just need to do:
float f = ...;
f = (float) Math.Ceiling (f);
rather than:
f = (float) ((double)f).Cei ling();
Not sure that's a particularly good reason though...

Thanks, Jon and Scott .
Your code works fine. I was just curious why decimal has methods like
Floor(). Round(), Truncate() , just no Ceiling().
BTW, in Microsoft SDK for Decimal.Round, I think there is a tiny error in
doc,
For example, when rounded to two decimals, the value 2.345 becomes 2.34 [
should be 2.35 ] and the value 2.355 becomes 2.36.
Best Wishes,

No, it should be 2.34, because Math.Round uses Banker's Rounding. Try
it - you'll get 2.34.

Hi,
I'm writing a program that has got a bit of maths in it. I perform a
division and then end up with something like 2.50, or 3.87, or 4.9975
(ie. y.12345).
I need to get rid of anything in front of the decimal point so that
I'm just left with the bit after the decimal point, ie. 0.50, 0.87,
0.9975, 0.12345 for the examples above.

Consider a rounding up function:
public static decimal RoundUp(decimal val, decimal round)
{
return ((decimal)Math.Ceiling((double)(val/round)))*round;
}
Math.Ceiling (and Math.Floor for RoundDown) only take double,s so we
need to cast twice. Is there a better way?

I have a database field that is the product of a multiply in a sql statement
and it sometimes has 5 or more decimal places. I want to truncate beyond
the 2nd decimal place(###.##). I figured a Ctype to a decimal value would
do that but the four decimal places remain. I found a truncate function but
it only truncates to whole numbers. how can I do the truncation?
Thanks,

Can someone tell me why the following statement gives me the result of 0 :
Math.Ceiling( 1 / 12);
Well actually the above is simplefied from :
private const int LocationsPerPage = 12;
(int)System.Math.Ceiling(dsLocations.Tables.Rows.Count /
LocationsPerPage);

Hi Guys,
I'm looking for a function that will return the lowest integer that is
greater than or equal to a decimal number.
eg.
3.1(decimal) returns 4(integer)
3.9(decimal) returns 4(integer)
4.0(decimal) returns 4(integer)

Hi,
Why does Math.Sqrt() only accept a double as a parameter? I would think
it would be just as happy with a decimal (or int, or float, or ....). I can
easily convert back and forth, but I am interested in what is going on behind
the scenes and if there is some aspect of decimals that keep them from being
used in this calculation.
Thanks!

Hi all,
I need to round a decimal value with a particular rule.
For example:
decimal a = 1.49m -1m
decimal a = 1.5m -1m
decimal a = 1.51m -2m
I've tried Math.Round but with the value 1.5 it returns me 2, which it is
not correct for my business rule.

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.
