There is a bug I have encountered.
The result shouldn't be -1 or 1.
Result are correct for some not for others.
But we can't know when it is correct or not.

Regards

Not limited with exponents.
nthroot() suffers from this bug too.

1. Whatever the exponentiation of (i)/(-i)
it has no mathematical meaning.
Win 7 rescues on either default complex or 1
2. Whatever the exponentiation of (-1)
it has no mathematical meaning.
Win 7 simply gives an error message
Differently, Mathcad 11 XP rescues (-1)^
on some complex default value or 1

You are wrong.
Exponentiation of -1 or i has mathematical meaning.
What means is your calculators don't have rectangular form.
I don't care if it has practical usage or not.
Mathematics has it, period.

This has nothing to do with Smath.
(-1)^0.36 is the Win Power Function X^Y fetched by Smath.
The X^Y is universal in all CAS.
That it does not evaluate some of your demand(s)
► complain to Microsoft, not in the Smath Community.
Doctor your demands as per the document in Samples.
There is another numerical pitfall wrt X^Y

No, it is wrong in SMath.
Other CAS softwares calculates it correctly.
Your are wrong here.

X^Y is not win power function. (whatever this gibberish means)
I am using linux, programming languages has nothing to do with windows.
If they are not specifically written for it of course.
Dot Net or C# is not specific to Windows.
You are wrong in here too.

X^Y is not universal in all CAS.
All computer assisted software can have different algorithms.
How can someone not know this basic information?
You are wrong here too.

You are wrong for all your claims. My demands are correct.
You lack a lot of knowledge about certain things.
You...

listed in the BTS, thank you.

BTW, since it was mentioned, .NET Framework exponentiation of double numbers returns NaN for complex results.
