numbers

i think this is very easy...isnt there a function that if i have a numbers like 4,3 4,5 4,6 4,9 it will always round it to 4? or 1,5 1,7 1,2 1,1 it will always round to 1?

If there is a possibility to change your type to decimal without a narrowing convertion you could use the Decimal classes Truncate method:

Code:

---

Dim a As Double = 467.923
MsgBox(Decimal.Truncate(CType(a, Decimal)))

Yeah its Math.Round:

VB Code:

MsgBox(Math.Round(4.9, 0))

Unfortunately the Math.Round function rounds to the nearest number, it's not rounding down only, as I think PT Exorcist wanted if I understood him correctly.

You can convert it to Int() if you just want to round down or drop the decimals.

MsgBox(Int(1.1))

Ahhh, easier than my convert to decimal thing. I tried CInt(4.9) but thet rounded up, missed the Int(4.9) one.

Nice Edneeis. :)

Thanks!

hmm in C# int(1.1) seems not to work =(

already did my own function lol...

PHP Code:

---

public static int lowerRound(double number)
{
    string temp = Convert.ToString(number);
    int pos;

    if (temp.IndexOf(",") > -1)
    {
        pos = temp.IndexOf(",");
    }
    else if(temp.IndexOf(".") > -1)
    {
        pos = temp.IndexOf(".");
    }
    else
    {
        throw (new ArgumentException("The given Number(" + number.ToString() + " is not a valid number"));
    }

    temp = temp.Substring(0,pos);

    return Convert.ToInt32(temp);
}

aah there is a SPECIFIC function for this! why dont you use this:

math.floor ()


there is also a math.ceiling function

ah lol..but now the function is done :eek:

hehe, I would still use this one. I'm not sure, but I guess it's faster than using int(), because it's written for this purpose only. You can throw your function in trashcap:D:D

lool whatever =P
