I consider this as a bug, too. My guess is, that it comes from the Singular
interface:
sage: R. = PolynomialRing(QQ, order='negdeglex')
sage: f = 1 + x
sage: I = R.ideal(x^2)
sage: import sage.libs.singular.function_factory
sage: reduce = sage.libs.singular.function_factory.ff.reduce
sage: reduce
Hi Samuel,
thank you for the interesting sources!
Best regards,

You can also group them together of somewhat reasonable size too (but don't

See https://trac.sagemath.org/ticket/22176 for a proposal based on a
discussion
About Sage and floating-point numbers, if I remember correctly,
- IEEE 754 is not a complete specification, some details are left
up to the implementation and therefore IEEE 754 compliant
computations can vary from machine to machine (depending
on processor or OS)
- in Sage, `RDF` and `float

I need someone to tell me where to propose three kinds of changes of
Sagemath.
(1) I guess Sagemath misses change log for some time.
(2) I also think documentation should reflect recent changes.
(3) I have am looking for ways of silencing deprecation warnings.
Concerning change logs...
