Hello,
I've been trying to convert gap complex number to Sage complex
numbers, and not doing well.
More precisely, given a gap object, x, that represents some number and
given a field,k, (coming from Sage), I'd like to find y\in k that
equivalent to x. While the math is obviously field specific, the code
seems to be so as well.
For example;
sage: x = gap('E(3) + E(10)')
sage: x
-E(15)^2+E(15)^4-E(15)^8-E(15)^11
sage: k = CyclotomicField(x.CONDUCTOR())
sage: k(x)
-zeta15^7 + zeta15^6 + zeta15^5 + zeta15^3 - zeta15^2 + 1
sage: CC(x)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
[....]
sage: y = k(x)
sage: CC(y)
0.309016994374948 + 1.45381065607691*I
Does anybody know of the way this should be done?
I guess this is related to this bug ;
