agena >> `The Power of Procedural Programming` 7.0.1 Vega, March 03, 2026 - `calc.zeros` can now alternatively compute complex roots. Examples: > calc.zeros(<: z -> z^3 - 1 :>): [1, -0.5-0.86602540378444*I, -0.5+0.86602540378444*I] > calc.zeros(<: z -> z^3 - 1 :>, guess = 0.5+I): [-0.5-0.86602540378444*I] - `member` now accepts a positive number as a third argument to set the maximum tolerance value if you want to see whether a number is part of a structure. Thus, you do no longer need to change the `Eps` environment variable (and change it back later) if you want a specific tolerance other than `Eps` for the comparison. Example: > member(20.000001, [10, 20, 30]): null > member(20.000001, [10, 20, 30], 1e-5): # 2 is the index of the number found 2 - `member` could potentially corrupt the stack when checking registers. This has been fixed. - New `debug.getk` returns the values internally treated as `constants` of the function in which it (i.e. `debug.getk`) has been called. It is a wrapper for `debug.getinfo(level, "k")`. Instead of a level, you may pass the function of interest. Example: > f := <: () with k := 101; j := k + 1 -> debug.getk() :> > f(): [101, 1, debug, getk] - You can now pass a function instead of a level to `debug.getlocals`. - New `debug.listcode` breaks down an Agena function into its opcode instructions and returns them in a table. Each line in it starts with the respective code line number in brackets. Example: > f := <: () > with k := 101; > j := k * 2 -> > k + j :> > for i in debug.listcode(f) do print(i) od ( 2) 0 - LOADK 0 0 ( 3) 1 - MUL 1 0 257 ( 4) 2 - ADD 2 0 1 ( 4) 3 - RETURN 2 2 0 ( 4) 4 - RETURN 0 1 0 - Two harmless bugs in the opcode management have been fixed.
