What's New:
- CLEAR REG is programmable in scientific flavors (did now allow to add this operation to a program)
- Advanced Scientific: matrixes may be larger than 33 elements in one dimension (did not allow either dimension to be larger than 33)
- Fix number rounding behavior for FRAC, INT, TEST, STO I, CF I, SF I, etc. (should round up but rounded down numbers like 9.99999999999999)
Many thanks to F. Vincent for the bug reports and insights!
