24ef677de7
Upgrade interval arithmetic.
...
* Move everything interval to a separate context (e.g. iv.exp must be used instead of mp.exp)
* Support both real and complex intervals (iv.mpf, iv.mpc)
* Fix interval cos/sin, and remove the old mpf_cos_sin code it depended on. The new interval cos/sin is a bit slower at low precision now, but this can be fixed.
* Implement interval atan2, and exp/log/power for complex intervals
* Move interval<->string code to libmpi
* Some other interface changes
More tests are still needed, and interface/utility functions needs more work.
