#369 closed defect (fixed)

basic arithmetic broken on 64-bit platforms

Reported by: felix winkelmann Owned by: felix winkelmann
Priority: major Milestone: 4.9.0
Component: unknown Version: 4.6.x
Keywords: arithmetic Cc:
Estimated difficulty:


On 64-bit systems, fixnum range can exceed the precision of doubles, which will generate sometimes incorrect results (due to the way overflow is currently detected). +, -, * and / will have to be reimplemented completely differently.
