Conversions in Dart

[Raquel Moreno]

What's up guys?  I need your help.

I know that Dart  is dynamically typed and all that stuff, but I'm wondering about how Dart works with narrowing conversion and widening conversion. Or it simply doesn't work with it? I read a lot of links on the internet and I dont conclude anything. Someone could light up my mind about it?

Thanks

The basic coercion mechanism is available as methods on the built-in classes. For instance, `print(3.14.toInt())` prints "3". Check out pages like https://api.dartlang.org/stable/dart-core/double-class.html for related methods like `ceil`, `floor`, and `truncate`.

Thanks

Dart has no automatic conversions, neither narrowing, widening, or otherwise.

Since Dart only has one integer type, a "bigint" that  supports arbitrary magnitude numbers, there is no need for narrowing or widening, nor is there any type to narrow or widen to.

In Dart 2 that may change if it introduces fixed-sized integers.
