Valore integrale massimo minore o uguale a d.
Se d è uguale a nan negativeinfinity o positiveinfinity verrà restituito tale valore.
Dim x as double math abs 50 3 dim y as double math abs 50 3 console writeline x console writeline y.
If d is equal to nan negativeinfinity or positiveinfinity that value is returned.
The following example illustrates the math ceiling double method and contrasts it with the floor double method.
Imports system math example abs.
The largest integral value less than or equal to d.
In order to determine whether a rounding operation involves a midpoint value the round method multiplies the original value to be rounded by 10 n where n is the desired number of fractional digits in the return value and then determines whether the remaining fractional portion of the value is greater than or equal to 5.
To use these functions without qualification import the system math namespace into your project by adding the following code to the top of your source file.
A number representing the largest integer less than or equal to the specified number.
The following example illustrates the math floor double method and contrasts it with the ceiling double method.
The largest integral value less than or equal to d if d is equal to nan negativeinfinity or positiveinfinity that value is returned.
The smallest integral value that is greater than or equal to a if a is equal to nan negativeinfinity or positiveinfinity that value is returned note that this method returns a double instead of an integral type.
This is a slight variation on a test for.
The floor method rounds a number downwards to the nearest integer and returns the result.
Math floor number in the above syntax number specifies the number to find the floor value.
Double examples use the math ceiling and math floor methods to compute ceiling and floors of doubles.
If the passed argument is an integer the value will not be rounded.
Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor.
Often numbers need to be manipulated.
Double values 7 03 7 64 0 12 0.
Nell esempio seguente viene illustrato il math floor double metodo e viene contrastato con.
Double values 7 03 7 64 0 12 0 12 7 1 7 6.
We can round a number upwards to the nearest integer with a ceiling function or down with a floor function.
Console writeline value ceiling floor n.
