#5684: [with patch, needs review] Taking negative powers of Laurent polynomial
throws exception
---------------------+------------------------------------------------------
Reporter: wjp | Owner: tbd
Type: defect | Status: new
Priority: major | Milestone: sage-3.4.1
Component: algebra | Keywords:
---------------------+------------------------------------------------------
Taking negative powers of a Laurent polynomial doesn't currently work due
to a typo in LaurentPolynomial_mpair.__pow__(). The attached patch fixes
this.
{{{
sage: F.<t> = LaurentPolynomialRing(GF(3))
sage: (1+t)^(-1)
TypeError: fraction_field() takes no arguments (1 given)
}}}
