Figure out what to do about operations on int values outside the comfortable JS range #638

Closed rakudrama closed 9 years ago

rakudrama commented 12 years ago

Issue #636 was that parsing hex literals resulted in incorrect values. However, the numbers are still represented by JavaScript doubles, leading to various incorrect values. Arithmetic operations are mostly correct up until rounding at 53 bits. Bitwise operations are truncated to 32 bits.

Here's a strawman:

* Make ints 32 bits in Frog.

Provide a "long" type implemented in Dart that works for arbitrary length arithmetic.
