What is Math.toDegrees() in Scala?

The toDegrees() function in Scala converts a radian value to degrees.

Figure 1 below shows a mathematical representation of the toDegrees() function:

Syntax

Double toDegrees(Double number)

Parameter

The toDegrees() function takes a numberradian value as a parameter.

Return value

The toDegrees() function then converts the radian value sent as a parameter to degrees.

If the parameter value is positive infinity, then it returns positive infinity.

If the parameter value is negative infinity, then it returns negative infinity.

If the parameter value is NaN, then it returns NaN.

Code

The following code shows how to use toDegrees() in scala.

import scala.math._
object Main extends App {
    //pi
    println(s"The value of toDegrees(Pi) = ${toDegrees(Pi)}"); 
    //pi/2
    println(s"The value of toDegrees(Pi/2) = ${toDegrees(Pi/2)}"); 
    //pi/4
    println(s"The value of toDegrees(Pi/4) = ${toDegrees(Pi/4)}"); 
    //0
    println(s"The value of toDegrees(0) = ${toDegrees(0)}"); 
    //-pi
    println(s"The value of toDegrees(-Pi) = ${toDegrees(-Pi)}"); 
    //-pi/2
    println(s"The value of toDegrees(-Pi/2) = ${toDegrees(-Pi/2)}"); 
    //-pi/4
    println(s"The value of toDegrees(-Pi/4) = ${toDegrees(-Pi/4)}"); 
    //error outputs
    println(s"The value of toDegrees(Double.PositiveInfinity) = ${toDegrees(Double.PositiveInfinity)}");
    println(s"The value of toDegrees(Double.NegativeInfinity) = ${toDegrees(Double.NegativeInfinity)}");
    println(s"The value of toDegrees(Double.NaN) = ${toDegrees(Double.NaN)}");
    
    
}
