The Haxe docs say that _Int_ represents _an integral number_.

What does that mean? I am guessing it means a 32-bit signed integer? Or perhaps, because of JavaScript’s influence, it means the integral part of an IEEE float-64?

Does Haxe have:

- longs (64-bit ints)
- IEEE float-32s
- unsigned ints and longs
- array/vector indexes that are longs

thanks

What it is, depends on the platform. See [Int](https://api.haxe.org/Int.html).

If you need to be specific, you can use [Int32](https://api.haxe.org/haxe/Int32.html) or [Int64](https://api.haxe.org/haxe/Int64.html).

The [Float](https://api.haxe.org/Float.html) is IEEE 64bit. Some platforms have other options, such as [Float32](https://api.haxe.org/cpp/Float32.html) for cpp, so you can provide target specific options in your code if you wish.

The same applies to UInt, which has some target specific types available to you.

Have a look through the API:

> **[top level - Haxe 4.3.7 API](https://api.haxe.org/)**

The upcoming Haxe 5.x is also previewing supporting for the [BigInteger](https://github.com/HaxeFoundation/haxe/issues/10750) type.
