LN(0.5) = positive!!!!! (solved)

[zarsoft]

Code:

DIM r1,r2 AS FLOAT

r1 = RND

r2 = (r1)
PRINT "r1=";r2

r2 = LN(r1)
PRINT "LN(r1)=";r2

Yes, the LN computation was bugged. Thanks for detecting it.
Try this new beta version and let me know if it works ok:

Works.
Thanks.

Í used this command:

C:> ZXBC -taB Test.bas
WARNING: deprecated flag --tap (use --output-format=tap instead)

Should I use another command?

[boriel]

You can still use the old one, but from here to 12 months, the old one will be removed.

At
https://zxbasic.readthedocs.io/en/latest/zxb/

where is

-H HEAP_SIZE, --heap-size HEAP_SIZE
--heap-size HEAP_ADDRESS


should be

-H HEAP_SIZE, --heap-size HEAP_SIZE
--heap-address HEAP_ADDRESS

Ok, I have updated the command line output
(still need to update the executable names, since zxb is now zxbc).
Also, please, better open a new thread for a different issue. This way we can close what is already done.

Also, I have created a Github Bug report form: https://github.com/boriel-basic/zxbasic/...new/choose
