Whole numbers

I've forgotten.

How do I round off numbers from an equation or round off to the third
decimal point for instance.

eg.
answers number is 12345.678910

I would like to see answer as 12345.67 or .68

Thanks

How do I round off numbers from an equation or round off to the third
decimal point for instance.


A simple method for rounding is to add 1/2 of the decimal place you wish
to round to, then perform an int function to remove the decimal point:

a=.4
a+=.5
a=int(a) 'a is now 0
a=1.26
a+=.05
a=int(a) ' a is now1.3

Look at the functions:

System.Math.Round
FormatNumber
System.Math.Floor
System.Math.Ceiling

Why not use System.Math.round or one of the many other rounding functions?

seems easier : )

To round the number itself, use the Math.Round static method.

For example, Math.Round(123.45678, 3) produces 123.457.

To leave the number with its full precision, but print a rounded number, use
String.Format().

For example, String.Format("{0:0.000}", 123.45678) produces the string
"123.457"

One caution: the Math.Round() function uses "banker's rounding" which,
rounds to even digits if the number is halfway between; for example,
123.4565 and 123.4555 both round to 123.456.

However, the String.Format() function appears to round up, so that 123.4565
rounds to "123.457".

But how about Banker's rounding? I suspect that's included somewhere but I
haven't found it yet.

Thanks for the help.

But I'd like to round to the second or third decimal point.

How do I do that?

a=.4
a+=.5
a=int(a) 'a is now 0
a=1.26
a+=.05
a=int(a) ' a is now1.3


Int will drop every thing to the right of the decimal place. So in this last
case a=1, not 1.3. The only way for this particular code to work is to shift
the number before and after the Int, as in:

a = 1.26
a += 0.05

a= Int(a * 10) / 10

I must be at least partially blind because I completely missed the
reference to banker's rounding the first time that I read your response.
Thank you for directing my attention to it so politely :)

At least no worse than I am! No need to choose weapons. Except perhaps a

Bob,
It appears that VS.NET 2005 (aka Whidbey, due out in 2005 sometime) will
have an option on Math.Round to use Banker's rounding or not.
