Comment (by iMark):
Hello jdemeyer. I'm also a developer of sagetides, as well as a tides
developer.
You are right with mpfr. From the very beginning we preset the number of
digits (binary or decimal) and all the floating point variables of the
code stores numbers of the same binary size.
We wrote 'N(parameter, digits = dig)' because, otherwise sage writes to
text either the algebraic representation of the number (eg pi) or an
insufficient floating point approximation.
However, using string representation, it is the same computational effort
parsing 0.10 0.100 or 0.1000000000, cause they have no exact
representation. I personally prefer long strings because it is more clear
for me to read so. I use sage as preprocessor to obtain C code to work
with and edit it outside sage environmet.
I hope this can clarify a bit the ticket.
