Qualified name: manim.mobject.text.numbers.DecimalNumber

class DecimalNumber(number=0, num_decimal_places=2, mob_class=<class 'manim.mobject.text.tex_mobject.MathTex'>, include_sign=False, group_with_commas=True, digit_buff_per_font_unit=0.001, show_ellipsis=False, unit=None, include_background_rectangle=False, edge_to_fix=array([-1., 0., 0.]), font_size=48, stroke_width=0, fill_opacity=1.0, **kwargs)

Bases: VMobject

An mobject representing a decimal number.

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()
