Introduction

A Python library for degree calculations and conversions.

🟩 Added in version 0.2: Supported pickle.

Installing

Python version	Windows	macOS / Linux
3.8 or 3.9	python -m pip install degrees==0.3.0.post1	pip3 install degrees==0.3.0.post1
3.10+	python -m pip install degrees	pip3 install degrees

If you use python 3.8 or 3.9, please read the docs here.

Importing

Just type import degrees.

Class

• class degrees.Degree(number)
  class degrees.Degree(degree_obj)
  class degrees.Degree(degree=0, minute=0, second=0)

  • Creating a Degree object

import degrees

print(degrees.Degree(1))  # 1°
print(degrees.Degree(2, 3, 4))  # 2°3'4"
print(degrees.Degree(1, second=2))  # 1°0'2"
print(degrees.Degree(1, 3))  # 1°3'
print(degrees.Degree(0, -1))  # -1'
print(degrees.Degree(1.5))  # 1°30'
print(degrees.Degree(2, -4))  # ValueError: if degree is not 0, minute and second must be positive integer

• calculating:

  expressions	type(a)	type(b)	return type
  a + b	Degree	int | float	Degree
  	int | float	Degree	Degree
  a - b	Degree	int | float	Degree
  	int | float	Degree	Degree
  a * b	Degree	int | float	Degree
  	int | float	Degree	Degree
  	Degree	Degree	Degree
  a / b	Degree	Degree	float
  	Degree	int | float	Degree
  math.trunc(a)	Degree	/	Degree
  abs(a)	Degree	/	Degree
  math.ceil(a)	Degree	/	Degree
  math.floor(a)	Degree	/	Degree
  a % b	Degree	Degree	Degree
  a // b	Degree	Degree	int
  	Degree	int | float	Degree
  +a	Degree	/	Degree
  -a	Degree	/	Degree
  hash(a)	Degree	/	int

  🟩 Added in version 0.1.7: Implemented the math.trunc function on the Degree objects.

  🟩 Added in version 0.4.0: Now deg_obj * float_obj is supported. In the previous version, only deg_obj * int_obj is supported.

  🟥 Deprecated since version 0.4.0, will be removed in version 0.5.0: Degree_obj * Degree_obj is deprecated because it is useless and strange.

• conversions:

  int(a)	float(a)	str(a)	repr(a)	bool(a)	complex(a)

  In the table above, type(a) is Degree.

  The complex(degree_obj) is different from degree_obj.to_complex(length). The former returns int(degree_obj)+0j, but the latter returns complex(length * cos(theta), length * sin(theta)), theta=degree2radian(degree_obj).

For example:

import degrees
a = degrees.Degree(45)
print(complex(a))  # (45+0j)
print(a.to_complex(2 ** 0.5))  # about (1+1j)

• comparisons:

  expressions	type(a)	type(b)
  a >= b	Degree	Degree | int | float
  a > b	Degree	Degree | int | float
  a == b	Degree	Any
  a <= b	Degree	Degree | int | float
  a < b	Degree	Degree | int | float
  a != b	Degree	Any

  In the table above, the return value is bool, type(a) and type(b) can be swapped.

• staticmethod from_str(string)

  Return a degree object from a string. The dms characters should be °, ' and ".

• staticmethod from_unicode(string)

  Similar to from_str, but the dms characters should be °, ′ and ″.

  🟩 Added in version 0.1.10.

• staticmethod from_iter(iterable)

  Return a degree object from an iterable.

• total_seconds

  The total seconds of a degree object.

• property deg

  The degree of a degree object(without sign).

• property min

  The minute of a degree object(without sign).

• property sec

  The second of a degree object(without sign).

• property sign

  The sign of a degree object.

• to_complex(length: int | float)

  Returns the complex number corresponding to (angle=self, radius=length).

  🟩 Added in version 0.2.1.

• property dms

  A tuple of (degree, minute, second).

Note

The attributes of Degree are read-only.

Functions

degrees.degree2radian(x: Degree, /)

• Convert angle x from a degree object to radians.

degrees.radian2degree(x: int | float, /)

• Convert angle x from radians to a degree object.

degrees.normalize(x: Degree, /)

• Used for angle normalization.
