[HL] Dynamic from Float vs any other target

```haxe
var f:Float = 3;
var test:Dynamic = f;
trace(Type.typeof(test));
f /= 2;
trace(f);
trace(Type.typeof(test));

Main.hx:39: TFloat
Main.hx:41: 1.5
Main.hx:42: TFloat

any other target

Main.hx:39: TInt
Main.hx:41: 1.5
Main.hx:42: TInt

```
HL looks better, it is strange to see value 1.5 and TInt type on other targets. Still, HL stands alone here. BTW, I tried to force TFloat using cast on the other targets, no success. Except adding some small fraction. While in case of HL, cast(value, Int) is working just fine to make type equal to other targets.
