Methods

Method	Description	Parameters	Returns
average	Calculates the weighted average of a list of numbers.	numbers (list) The list of numbers to calculate the average of. weights (list) The list of weights.	DecimalNumber The average of the numbers.
floor	Returns the floor of a number.	number The number to calculate the floor of. digits Digits amount to cut from the number.	number type The floor of the number.
is_all_numbers	Checks if all elements in a list are numbers.	elements (list) The list of elements to check.	bool True if all elements are numbers, False otherwise.
max	Returns the maximum number from variable elements, which can be numbers or an iterable objects like list.	*elements Variable arguments, which can be numbers or an iterable objects like list.	number type The maximum number in the list.
min	Returns the minimum number from variable elements, which can be numbers or an iterable objects like list.	*elements Variable arguments, which can be numbers or an iterable objects like list.	number type The minimum number in the list.
sum_0_to_n	Returns the sum of numbers from 0 to n.	n The number to sum up to.	number type The sum of numbers from 0 to n.

Examples:

• MathUtil.average

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Calculate the weighted average of a list of numbers
  average = MathUtil.average([1, 2, 3, 4, 5], [1, 5, 6, 7, 8])
  
  print(average)
  

  Output

  3.592593
  

• MathUtil.floor

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Calculate the floor of a number
  floor = MathUtil.floor(3.14159, 2)
  
  print(floor)
  

  Output

  3.14
  

• MathUtil.is_all_numbers

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Check if all elements in a list are numbers
  is_all_numbers = MathUtil.is_all_numbers([1, 2, 3, 4, 5])
  
  print(is_all_numbers)
  

  Output

  True
  

• MathUtil.max

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Get the maximum number from a list
  max_number = MathUtil.max(1, [2, 7, [8, 9]], 3, 4, 5)
  
  print(max_number)
  

  Output

  9
  

• MathUtil.min

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Get the minimum number from a list
  min_number = MathUtil.min(1, [2, 7, [0, 9]], 3, 4, 5)
  
  print(min_number)
  

  Output

  0
  

• MathUtil.sum_0_to_n

  Code

  from nrt_math_utils.math_utils import MathUtil
  
  # Get the sum of numbers from 0 to n
  sum_0_to_n = MathUtil.sum_0_to_n(5)
  
  print(sum_0_to_n)
  

  Output

  15
  

DecimalNumber class

Represents a decimal number with a fixed number of decimal places.

Examples:

• Create a DecimalNumber object

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create a DecimalNumber object with a value of 3.14159 and 2 decimal places
  decimal_number = DecimalNumber(3.14159, 2)
  
  print(decimal_number)
  

  Output

  3.14
  

• Create a DecimalNumber object with default decimal places

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create a DecimalNumber object with a value of 3.14159 and default 6 decimal places
  decimal_number = DecimalNumber(3.1415926535897)
  print(decimal_number)
  

  Output

  3.141593
  

• Add two DecimalNumber objects

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create two DecimalNumber objects
  decimal_number_1 = DecimalNumber(3.14159, 2)
  decimal_number_2 = DecimalNumber(2.71828, 2)
  
  # Add the two DecimalNumber objects
  result = decimal_number_1 + decimal_number_2
  
  print(result)
  

  Output

  5.86
  

• Subtract a number from DecimalNumber

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create a DecimalNumber object
  decimal_number = DecimalNumber(3.14159, 2)
  
  # Subtract a number from the DecimalNumber object
  result = decimal_number - 1.23456
  
  print(result)
  

  Output

  1.91
  

• Multiply DecimalNumber with other number

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create a DecimalNumber object
  decimal_number = DecimalNumber(3.14159, 2)
  
  # Multiply the DecimalNumber object with another number
  result = decimal_number * 2
  
  print(result)
  

  Output

  6.28
  

• Compare DecimalNumber to other number

  Code

  from nrt_math_utils.nrt_numbers import DecimalNumber
  
  # Create a DecimalNumber object
  decimal_number = DecimalNumber(3.14159, 2)
  
  # Compare the DecimalNumber object to another number
  result = decimal_number > 3.14
  
  print(result)
  

  Output

  True
