For the record, you can generally find the "API" version of a GP
command/function with '??':
=====================
? ??nfrootsof1
nfrootsof1(nf):
computes the number of roots of unity w and a primitive w-th root
of unity (expressed on the
integral basis) belonging to the number field nf. The result is a
two-component vector [w,z]
where z is a column vector expressing a primitive w-th root of
unity on the integral basis
nf.zk.
The library syntax is rootsof1(nf).
=====================
Of course, in SAGE, it's tough to tell:
? ??nfrootsof1
sh: line 1: /SandBox/Justin/sb/sage-2.7.1/local/bin/gphelp: No such
file or directory
(I don't think we install the doc).
