There seem to be 2 cases which would help me to complete some sage code
1) Complex Fractions fraction∗I like 4.4747038862752024491936821935697961325∗I
2) Numbers of the form number∗N±12 like , 3623680665059√38,179398994850√38
Using the function .canonicalize_radical() , I get the error.
PARI/GP ERROR: * at top-level: sage[1296]=canonicalize_radical(sage[1264]) ^-------------------------------- ** not a function in function call
I hope there is a solution in sage
