ceil()

The ceil() method in Kotlin’s math library rounds a floating-point number up to the nearest integer.

Syntax

kotlin.math.ceil(x)

• x: A value of type Double or Float to be rounded up.

Example

The following code demonstrates a basic implementation of the ceil() method.

val myDouble: Double = 7.5
val myFloat: Float = 6.3f
val myInt: Int = 4

val resultDouble: Double = ceil(myDouble)
val resultFloat: Float = ceil(myFloat)
val resultInt: Double = ceil(myInt.toDouble())

fun main() {
  println(resultDouble)
  println(resultFloat)
  println(resultInt)
}

This will return the following output:

8.0
7.0
4.0
