calculator-mgaidy 0.0.7

A small example package

Calculator_mgaidy

Overview

A basic calculator class that supports arithmetic operations and maintains a history log.

Installation

You can install the Calculator_mgaidy package using pip:

pip install calculator-mgaidy==0.0.7

Attributes

• memory (float): The current memory value of the calculator.
• logs (List[str]): A list to store the history log of operations.
• precision (int): The precision to round results to.

Constants

• MAX_NUMBER (float): The maximum allowed absolute value of number in calculations.
• MAX_POWER_LEVEL (int): The maximum allowed power level for exponentiation.
• MAX_PRECISION (int): The maximum allowed power level for exponentiation.

Methods

Each of the functions below have validations set in place to ensure that inputs and results are allowed values. Precision must be more than zero but less than 300. By default 10. Numbers maximum allowed absolute value is 1e300. (applies to input and output) Power and root inputs must be more than zero but less than 300.

set_precision(self, precision: int) -> None

Set the precision for rounding results.

reset_memory(self) -> float

Reset the calculator memory to zero and clear the history log.

print_history_logs(self) -> None

prints out log of operations since last reset.

add(self, number: float) -> float

Add a number to the calculator memory.

subtract(self, number: float) -> float

Subtract a number from the calculator memory.

multiply(self, number: float) -> float

Multiply the calculator memory by a number.

divide(self, number: float) -> float

Divide the calculator memory by a number.

power(self, number: float) -> float

Raise the calculator memory to the power of a given number.

root(self, number: float) -> float

Calculate the root of the calculator memory with a given exponent.

Usage Example

from calculator import Calculator

# Create a calculator instance
calc = Calculator()

# Perform operations
result = calc.add(5)
print(result)  # Output: 5.0

result = calc.multiply(3)
print(result)  # Output: 15.0

Development

For development, ensure that you have Python and pip installed. You can set up a virtual environment:

source venv/bin/activate  # On Windows, use `venv\Scripts\activate`
