2.1.2 Overflow

For performance reasons, the Haxe Compiler does not enforce any overflow behavior. The burden of checking for overflows falls to the target platform. Here are some platform specific notes on overflow behavior:

• C++, Java, C#, Neko, Flash: 32-bit signed integers with usual overflow practices
  • PHP, JS, Flash 8: No native Int type, loss of precision will occur if they reach their float limit (2⁵²)

Alternatively, the haxe.Int32 and haxe.Int64 classes can be used to ensure correct overflow behavior regardless of the platform at the cost of additional computations depending on the platform.
