Very simple proposal. Add an extension function to

Double

so you can do this:

0.5.toBigDecimal()

Isn't it considered bad practice to create a BigDecimal from a Double or Float?

You can create an extension property:

val <http://Double.bd|Double.bd> : BigDecimal get() = BigDecimal(this)

val value = 0.5.bd

It is coming in Kotin 1.2. https://blog.jetbrains.com/kotlin/2017/06/early-access-program-for-kotlin-1-2-has-been-started/

I'd prefer it as

fun Double.toBigDecimal()

, because that's a conversion function, just like

toMutableList

.

@dmitry.petrov Isn't that what's coming in 1.2?

Yes it is. Just explained what I don't like about

.bd

Ah, sorry. I though you were responding to @elizarov, so I got a bit confused.
