classmethod Config.set_fmt_float(
    fmt: FloatFmt | None = 'mixed',
) → type[Config]

“mixed” float formatting:

>>> s = pl.Series([1.2304980958725870923, 1e6, 1e-8])
>>> with pl.Config(set_fmt_float="mixed"):
...     print(s)
shape: (3,)
Series: '' [f64]
[
    1.230498
    1e6
    1.0000e-8
]

“full” float formatting:

>>> with pl.Config(set_fmt_float="full"):
...     print(s)
