What's new in Free42
Fixed complex SQRT so it returns exact results when Re(x) = 0 and Im(x)/2 is a perfect square.
VARMENU would step through rows of multi-line menus in the wrong order. (You needed a function with 13 or more MVARs to notice this.) Fixed.
When printing to GIF, changing the filename did not cause the GIF numbering sequence to restart at 1. Fixed.
When printing to GIF, output files are now flushed and closed immediately when they reach their maximum height.
