    Parameters
    ----------
    var : Union[:class:`int`, :class:`float`]
        The initial value you need to keep track of and display.
    label : Union[:class:`str`, :class:`~.Tex`, :class:`~.MathTex`, :class:`~.Text`, :class:`~.TexSymbol`, :class:`~.SingleStringMathTex`]
        The label for your variable. Raw strings are convertex to :class:`~.MathTex` objects.
    var_type : Union[:class:`DecimalNumber`, :class:`Integer`], optional
        The class used for displaying the number. Defaults to :class:`DecimalNumber`.
    num_decimal_places : :class:`int`, optional
        The number of decimal places to display in your variable. Defaults to 2.
        If `var_type` is an :class:`Integer`, this parameter is ignored.
    kwargs : Any
            Other arguments to be passed to `~.Mobject`.

    Attributes
    ----------
    label : Union[:class:`str`, :class:`~.Tex`, :class:`~.MathTex`, :class:`~.Text`, :class:`~.TexSymbol`, :class:`~.SingleStringMathTex`]
        The label for your variable, for example ``x = ...``.
    tracker : :class:`~.ValueTracker`
        Useful in updating the value of your variable on-screen.
    value : Union[:class:`DecimalNumber`, :class:`Integer`]
        The tex for the value of your variable.
