# Kotlin Class: MathConstants object for Mathematical constants

## Kotlin Class: Exercise-20 with Solution

Write a Kotlin program that creates an object declaration 'MathConstants' that provides constants for mathematical calculations such as PI and E.

Sample Solution:

Kotlin Code:

``````object MathConstants {
val PI = 3.14159
val E = 2.71828
}

fun main() {
println("Value of PI: \${MathConstants.PI}")
println("Value of E: \${MathConstants.E}")
}
```
```

Sample Output:

```Value of PI: 3.14159
Value of E: 2.71828
```

Explanation:

In the above exercise -

• First we define an object declaration "MathConstants" which serves as a singleton object. Inside the MathConstants object, we define two properties PI and E to hold mathematical constants.
• In the "main()" function, we access PI and E values using the MathConstants object and print them.
