That looks like C#, not C++!

I have taken this text from the VS 6.0 help, but without seeing from which library. It is java. Sorry for the confusion.

In general, rounding is needed when you want to display the number as a string. Is that the case for you ?
If yes, you can use sprintf and specify a precision:
char szBuff[25];<br />
sprintf(szBuff,"%.2f",yourDouble);
This tells sprintf to print 2 decimals after the floating point.
If you need to use it as a double (and not a string), you can multiply it by 100, convert it to an int and divided it back by 100.0:
double yourDouble = 0.00922307;<br />
int yourInt = yourDouble * 100;<br />
double roundedDouble = yourInt / 100.0;
(you must be carefull and divide by 100.0, not by 100, otherwise the you will end up with an integer and not a double).

but as per logic it returns 0.00 not 0.01 which required.

I think
double yourDouble = 0.00922307 + .005;
will be more right.

Yes, you are perfectly right 
I forgot that the rounding is always rounded-down.

This is another way to do that.
I did it with VC++ 6.0 to be used in my project. The return value is a string to be shown in the GUI, but you can easily adapt it just for numbers.
CString CMyDoc::CutAndRoundStringToNDecimals (double dValue, const int nDec)
{ double dTemp = 0, dFract = 0, dInt = 0, dRes = 0;
int nCount = 0;
CString cLetter = "";
dTemp = dValue*pow(10,nDec);
dFract = modf (dTemp, &dInt);
if (dFract >= 0.5)
dInt++;
dRes = dInt/pow(10,nDec);
CString szResult;
szResult.Format ("%s%f", szResult, dRes);
int nLarge = szResult.GetLength ();
for (int i = 0; i < nLarge; i++)
{ nCount++;
CString cLetter = szResult.GetAt (i);
if (cLetter == ".")
{ nCount += nDec;
break;
}
}
LPTSTR pStr = szResult.GetBufferSetLength (nCount);
szResult.ReleaseBuffer ();
return szResult;
}
Hope it helps
I forgot to say that math.h has to be included to use pow () and modf()

Hello,
i have come across with the int version of this function somewhere and changed to double in order to avoid precision problems for big and small values. You may use the int version if it fits your requirement.
double roundExt(double Num, double Seed)
{
// get rational factor
double fac = Num / Seed;
// get natural factor
fac = (fac < 0) ? (ceil(fac - 0.5)) : (floor(fac + 0.5));
// fac = (fac < 0) ? static_cast<int>(fac-0.5) : static_cast<int>(fac+0.5);
// return multiple
return fac * Seed;
}
roundExt(0.009,0.01); is the usage.
Hope this helps.
Bekir.

Very urgent is somewhat subjective. Could you please rate the urgency on a scale of 1 to 10 where 1 is "I couldnt care less" and 10 is "if I dont find a toilet it's going to be messy"
|
|
|
|
|
"PeePee, Daddy, PeePee!"
Thats urgency! Toilet NOW, not in a minute or so.
