# DecimalMatrix¶

Qualified name: `manim.mobject.matrix.DecimalMatrix`

class DecimalMatrix(matrix, element_to_mobject=<class 'manim.mobject.text.numbers.DecimalNumber'>, element_to_mobject_config={'num_decimal_places': 1}, **kwargs)[source]

Bases: `Matrix`

A mobject that displays a matrix with decimal entries on the screen.

Examples

Example: DecimalMatrixExample

```from manim import *

class DecimalMatrixExample(Scene):
def construct(self):
m0 = DecimalMatrix(
[[3.456, 2.122], [33.2244, 12]],
element_to_mobject_config={"num_decimal_places": 2},
left_bracket="\{",
right_bracket="\}")
```
```class DecimalMatrixExample(Scene):
def construct(self):
m0 = DecimalMatrix(
[[3.456, 2.122], [33.2244, 12]],
element_to_mobject_config={"num_decimal_places": 2},
left_bracket="\{",
right_bracket="\}")

```

Will round/truncate the decimal places as per the provided config.

Parameters:
• matrix (Iterable) – A numpy 2d array or list of lists

• element_to_mobject (Mobject) – Mobject to use, by default DecimalNumber

• element_to_mobject_config (dict[str, Mobject]) – Config for the desired mobject, by default {“num_decimal_places”: 1}

Methods

Attributes

 `animate` Used to animate the application of any method of `self`. `animation_overrides` `color` `depth` The depth of the mobject. `fill_color` If there are multiple colors (for gradient) this returns the first one `height` The height of the mobject. `n_points_per_curve` `sheen_factor` `stroke_color` `width` The width of the mobject.
_original__init__(matrix, element_to_mobject=<class 'manim.mobject.text.numbers.DecimalNumber'>, element_to_mobject_config={'num_decimal_places': 1}, **kwargs)

Will round/truncate the decimal places as per the provided config.

Parameters:
• matrix (Iterable) – A numpy 2d array or list of lists

• element_to_mobject (Mobject) – Mobject to use, by default DecimalNumber

• element_to_mobject_config (dict[str, Mobject]) – Config for the desired mobject, by default {“num_decimal_places”: 1}
