Le type float a une
précision limitée. Il s'agit de nombres flottant double
précision.

Extrait du manuel de référence du manuel : "These represent
machine-level double precision floating point numbers. You
are at the mercy of the underlying machine architecture (and C or
Java implementation) for the accepted
range and handling
of overflow. Python does not support single-precision floating
point numbers; the savings in processor and
memory usage that are usually the reason for using these is
dwarfed by the overhead of using objects in Python, so there is
no reason to complicate the language with two kinds of floating
point numbers."
