Examples

Example: MovingSquareWithUpdaters

from manim import *

class MovingSquareWithUpdaters(Scene):
    def construct(self):
        decimal = DecimalNumber(
            0,
            show_ellipsis=True,
            num_decimal_places=3,
            include_sign=True,
        )
        square = Square().to_edge(UP)

        decimal.add_updater(lambda d: d.next_to(square, RIGHT))
        decimal.add_updater(lambda d: d.set_value(square.get_center()[1]))
        self.add(square, decimal)
        self.play(
            square.animate.to_edge(DOWN),
            rate_func=there_and_back,
            run_time=5,
        )
        self.wait()

get_formatter(**kwargs)[source]

Configuration is based first off instance attributes, but overwritten by any kew word argument. Relevant key words: - include_sign - group_with_commas - num_decimal_places - field_name (e.g. 0 or 0.real)

set_value(number)[source]

Set the value of the DecimalNumber to a new number.

Parameters

number (float) – The value that will overwrite the current number of the DecimalNumber.
