Why it is "p≤0.05" but not exact number?

[huajiasha]

test code below

    pairs = [
        ("PBS", "OVA")
    ]
    annot = Annotator(ax2, pairs,fontsize=10, **plotting_parameters)
    annot.configure(test='Mann-Whitney', text_format='simple', loc='inside',show_test_name=False, verbose=2)
    annot.apply_test()

the p value is 1.476e-02 or 0.01476, it is far from 0.05

Passing `palette` without assigning `hue` is deprecated and will be removed in v0.14.0. Assign the `x` variable to `hue` and set `legend=False` for the same effect.
