Scala - Math hypot() Method
The Scala Math hypot() method returns square root of sum of squares of two arguments, i.e., sqrt(x2 +y2). In special cases it returns the following:
- If either argument is infinity, then the result is positive infinity.
- If either argument is NaN and neither argument is infinite, then the result is NaN.
Syntax
def hypot(x: Double, y: Double): Double = java.lang.Math.hypot(x, y)
Parameters
x |
Specify a value. |
y |
Specify a value. |
Return Value
Returns sqrt(x2 +y2).
Exception
NA.
Example:
In the example below, hypot() method returns sqrt(x2 +y2).
import scala.math._
object MainObject {
def main(args: Array[String]) {
println(s"hypot(3, 4) = ${hypot(3, 4)}");
println(s"hypot(5, 12) = ${hypot(5, 12)}");
println(s"hypot(8, 15) = ${hypot(8, 15)}");
println(s"hypot(8, -15) = ${hypot(8, -15)}");
println(s"hypot(10, Double.NaN) = ${hypot(10, Double.NaN)}");
println("hypot(10, Double.PositiveInfinity) = "
+ hypot(10, Double.PositiveInfinity));
println("hypot(Double.PositiveInfinity, Double.NaN) = "
+ hypot(Double.PositiveInfinity, Double.NaN));
}
}
The output of the above code will be:
hypot(3, 4) = 5.0 hypot(5, 12) = 13.0 hypot(8, 15) = 17.0 hypot(8, -15) = 17.0 hypot(10, Double.NaN) = NaN hypot(10, Double.PositiveInfinity) = Infinity hypot(Double.PositiveInfinity, Double.NaN) = Infinity
