NullPointerException, Kotlin, Square root of BigDecimal?

Question

Java

val epsilon = 0.000000000000000000000001.toBigDecimal()
private val accuracy = MathContext(1000)
private val maxIteration = maxIteration
private fun doElipticK():BigDecimal{
        println(epsilon)
        val epsilonSqrt = epsilon.sqrt(accuracy)

So the code works, but as soon as we add 0.0000000000000000000000001 to the number, we get an exception, in which direction should we look?

val epsilon = 0.000000000000000000000002.toBigDecimal()
private val accuracy = MathContext(1000)
private val maxIteration = maxIteration
private fun doElipticK():BigDecimal{
        println(epsilon)
        val epsilonSqrt = epsilon.sqrt(accuracy)

NullPointerException

Answer 1

What line is your NPE on?

Answer 2

Eh kotlin, kotlin...
To begin with, it would be possible to debug so that people here have an understanding on which line your code is crashing. Based on my guesses (I don’t know Kotlin), doEliptick is some kind of method that it does hidden from us. I put 5 kopecks on the fact that if this is a method, then it falls in it.
In general, you need to debug, and then you yourself will understand what the problem is. You will not understand - throw here the full code and a line on which falls.
