Creating BigDecimal


#1

In an video, I saw the syntax

val one = 1.bd

but it doesn’t work for me. So I defined

fun Int.bd() : BigDecimal? = BigDecimal(this)

and now I can write

val one = 1.bd()

Nice, but according to what I read, parentheses are optional, but it doesn’t work. Are parentheses mandatory or what’s gong on here?

hello,

Look this example http://kotlin-demo.jetbrains.com/?publicLink=114553589811306443494-1930716178

What you want is extension properties. You declared extension method. Read details here http://kotlinlang.org/docs/reference/extensions.html

About optional parentheses. I think you mean infix notation. Read details here http://kotlinlang.org/docs/reference/functions.html

Perfect. I’re read about extension properties, but have forgotten it all.

That’s it.

I’ve seen that a question has been marked as answered, but I don’t see how?
