Code Sample, a copy-pastable example if possible

import pandas as pd
float_val = 0.55555555
index=pd.MultiIndex.from_tuples([(float_val,float_val)], names=[float_val,float_val])
df = pd.DataFrame([float_val], index=index, columns=index)
pd.set_option('display.precision', 3)
df
0.55555555 0.556
0.55555555 0.556
0.55555555 0.55555555
0.556 0.556 0.556
