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

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()
