I have the following account:
var NumeroDePaginas = NumeroDeItens / 32;
When I use Math.Round it rounds both up and down. But whenever there is any decimal value I want to return an integer value rounded up.
Example: If NumeroDeItens / 32 is equal to 1.01, NumeroDePaginas will equal 2.
How do I get this result?
Use Math.Ceiling (), example:
var valorArredondado = Math.Ceiling(1.01);
Example taken from MSDN:
double[] values = {7.03, 7.64, 0.12, -0.12, -7.1, -7.6};
Console.WriteLine(" Value Ceiling Floor\n");
foreach (double value in values)
Console.WriteLine("{0,7} {1,16} {2,14}",
value, Math.Ceiling(value), Math.Floor(value));
// The example displays the following output to the console:
// Value Ceiling Floor
//
// 7.03 8 7
// 7.64 8 7
// 0.12 1 0
// -0.12 0 -1
// -7.1 -7 -8
// -7.6 -7 -8
Note: When using Math.Ceiling (), if there is a division of integers, an error may occur indicating incompatibility between decimal and double, in this case, you must force the result to be of type double, eg:
var valorArredondado = Math.Ceiling(3 / 32d);
Where the letter d after the number indicates that 32 will be double.
