This is a long overdue release with mainly bug fixes such as the following:
- Sometimes parts of a graph became invisible (especially
sqrtandlnfunctions). These are fixed now. - There were rounding issues with certain kind of numeric computations. One example is
10.02-10.01. It produced a slightly off value (0.00999…) as Java’s builtin arithmetic operations are not accurate enough. Now the results are rounded and the output is the correct value.
The release also has a new feature – double factorials. Double factorials (wikipedia) are like factorials but only multiply odd/even numbers. Examples: 6!!=2*4*6=48 or 5!!=1*3*5=15
