Is there in Sagemath something like RealDigits in Mathematica for computing (binary) digits of any real number? (and not only for integers)
Can you please also explain how to transform back a non-integer binary string as '100.1000111001001' to the corresponding (approximated) base ten decimal? (not float)
To get the binary representation just add a .str(base=2) to the approximated value.
sage: a = pi + sqrt(2)
sage: a.n(digits=10).str(base=2)
'100.1000111001001001010100001111000010'
For the other direction the method RR is useful. Given as first argument the string and as second the base.
sage: s= a.n(digits=60).str(base=2)
sage: RR(s,2)
