Mathematics Utilities

Mathematics utilities in Python.

MathUtil class

Methods

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
