That would be an easy impression to get from this long rambling thread.
The argument that Python's ‘float’ type is not meant to be anything
*but* an IEEE 754 floating point type has been made several times.

What would you say Python's ‘float’ type is intended to be, if not an
IEEE 754 floating point type?
