Hi, all,
I want to create a "function" within a function, and return it as the value of
the latter function, something along the lines of:
def g(a,b,c):
var('x y')
f = a*x^2 + b*y + c
return f
This works, almost. I have to invoke the return value as a function returning
a functio
Hi, all,
I do this, and get integers, but the types are rational:
sage: b1=0
sage: b2=2
sage: s=(b1+b2)/2
sage: n=(b1-b2)/2
sage: s
1
sage: n
-1
Then I do this:
sage: xgcd(s,n)
