I learn Sage to compute Gröbner bases.
Concerning polynomial ring, if I type:
R = PolynomialRing(QQ, 't')
R
I get:
Univariate Polynomial Ring in t over Rational Field
But if I type:
R = PolynomialRing(RR, 't')
R
I get:
Univariate Polynomial Ring in t over Real Field with 53 bits of precision
What does "with 53 bits of precision" mean? If I don't know its meaning, will it matter when I compute Gröbner bases? I would appreciate any help with this situation.KarlTue, 27 Dec 2016 08:46:22 -0600http://ask.sagemath.org/question/36103/
