[Jython-dev] math.sqrt behavior difference

[Michael B. <m...@bu...>]

Hi,

There's a difference in behavior between CPython 2.7 and latest jython hg sources:

> 0mb@wiggum:~/develop/hg/jython$ python2 -c 'import math; print(math.sqrt(-1.5))'
> Traceback (most recent call last):
>   File "<string>", line 1, in <module>
> ValueError: math domain error
> 1mb@wiggum:~/develop/hg/jython$ ./dist/bin/jython -c 'import math; print(math.sqrt(-1.5))'
> nan

Is this expected?

This requires workarounds in my code as-is. I would prefer, if jython behavior was changed
to match CPython.
