calculator

Provide several sample math calculations.

This module allows the user to make mathematical calculations.

Examples:

>>> from calculator import calculations
>>> calculations.add(2, 4)
6.0
>>> calculations.multiply(2.0, 4.0)
8.0
>>> from calculator.calculations import divide
>>> divide(4.0, 2)
2.0

The module contains the following functions:

  • add(a, b) - Returns the sum of two numbers.
  • subtract(a, b) - Returns the difference of two numbers.
  • multiply(a, b) - Returns the product of two numbers.
  • divide(a, b) - Returns the quotient of two numbers.

Functions:

  • add –

    Compute and return the sum of two numbers.

  • divide –

    Compute and return the quotient of two numbers.

  • multiply –

    Compute and return the product of two numbers.

  • subtract –

    Calculate the difference of two numbers.

add 

add(a: int | float, b: int | float) -> float

Compute and return the sum of two numbers.

Examples:

>>> add(4.0, 2.0)
6.0
>>> add(4, 2)
6.0

Parameters:

  • a (int | float) –

    A number representing the first addend in the addition.

  • b (int | float) –

    A number representing the second addend in the addition.

Returns:

  • float –

    A number representing the arithmetic sum of a and b.

divide 

divide(a: int | float, b: int | float) -> float

Compute and return the quotient of two numbers.

Examples:

>>> divide(4.0, 2.0)
2.0
>>> divide(4, 2)
2.0
>>> divide(4, 0)
Traceback (most recent call last):
...
ZeroDivisionError: division by zero

Parameters:

  • a (int | float) –

    A number representing the dividend in the division.

  • b (int | float) –

    A number representing the divisor in the division.

Returns:

  • float –

    A number representing the quotient of a and b.

Raises:

multiply 

multiply(a: int | float, b: int | float) -> float

Compute and return the product of two numbers.

Examples:

>>> multiply(4.0, 2.0)
8.0
>>> multiply(4, 2)
8.0

Parameters:

  • a (int | float) –

    A number representing the multiplicand in the multiplication.

  • b (int | float) –

    A number representing the multiplier in the multiplication.

Returns:

  • float –

    A number representing the product of a and b.

subtract 

subtract(a: int | float, b: int | float) -> float

Calculate the difference of two numbers.

Examples:

>>> subtract(4.0, 2.0)
2.0
>>> subtract(4, 2)
2.0

Parameters:

  • a (int | float) –

    A number representing the minuend in the subtraction.

  • b (int | float) –

    A number representing the subtrahend in the subtraction.

Returns:

  • float –

    A number representing the difference between a and b.
