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)

By the way, an excellent ressource to teach those kind of things and
check carefully what happens is the sign_mantissa_exponent method:
sage: a = RR(1.1)
sage: a
1.10
sage: a.sign_mantissa_exponent()
