How to convert a negative number to positive in python?

To convert a negative number to its positive equivalent in Python, you can use the built-in abs() function, which returns the absolute (positive) value of a number. Here's how you can do it:

# Negative number negative_number = -5 # Convert to positive positive_number = abs(negative_number) print(positive_number) # Output: 5

In this example, we start with a negative number, -5, and then use the abs() function to obtain its positive equivalent, which is 5. The abs() function works for both integers and floating-point numbers.

Examples

  1. Convert negative number to positive in Python using abs():

    • Description: This approach involves using the built-in abs() function in Python, which returns the absolute value of a number, effectively converting negative numbers to positive.
    • Code:
      num = -5 positive_num = abs(num)

  2. Python convert negative number to positive with conditional statement:

    • Description: This method involves using a conditional statement to check if the number is negative and then multiplying it by -1 to convert it to a positive number.
    • Code:
      num = -5 positive_num = num if num >= 0 else -num

  3. Convert negative number to positive in Python using multiplication by -1:

    • Description: This approach involves multiplying a negative number by -1, which results in its positive equivalent.
    • Code:
      num = -5 positive_num = num * -1

  4. Python convert negative number to positive with math module:

    • Description: This method involves using the math.fabs() function from the math module, which returns the absolute value of a floating-point number.
    • Code:
      import math num = -5 positive_num = math.fabs(num)

  5. Convert negative number to positive in Python using bitwise complement:

    • Description: This approach involves using the bitwise complement operator (~) along with bitwise AND (&) to convert negative numbers to positive.
    • Code:
      num = -5 positive_num = ~num + 1

  6. Python convert negative number to positive with numpy absolute():

    • Description: This method involves using the numpy.absolute() function from the NumPy library, which returns the absolute value of an array-like object.
    • Code:
      import numpy as np num = -5 positive_num = np.absolute(num)

  7. Convert negative number to positive in Python using sign():

    • Description: This approach involves using the math.copysign() function from the math module, which returns a number with the magnitude of the first argument and the sign of the second argument.
    • Code:
      import math num = -5 positive_num = math.copysign(num, 1)

  8. Python convert negative number to positive with ternary operator:

    • Description: This method involves using a ternary operator to check if the number is negative and then returning its positive equivalent.
    • Code:
      num = -5 positive_num = num if num >= 0 else -num

  9. Convert negative number to positive in Python using conditional expression:

    • Description: This approach involves using a conditional expression to check if the number is negative and then converting it to positive using multiplication by -1.
    • Code:
      num = -5 positive_num = num if num >= 0 else num * -1

  10. Python convert negative number to positive with numpy sign():

    • Description: This method involves using the numpy.sign() function from the NumPy library, which returns an element-wise indication of the sign of a number.
    • Code:
      import numpy as np num = -5 positive_num = np.sign(num) * num
