scipy-calculator 0.0.4

A Scientific calculator

Scientific Python Calculator

Scientific Python Calculator (scipy_calculator) is a library for doing mathematics computation. It works similar to a calculator.

:raised_hands: This is my first python package. It will be improved over time. Feel free to contribute to this beautiful work of art.

Installation

:warning: scipy_calculator is only tested with python 3.

Installation via PYPI

$ pip install scipy-calculator

Installation via Github this is for the stable released version

$ pip install git+https://github.com/komus/scipy_calculator

scipy_calculator uses multipledispatch dependency and pytest for automated test

Usage

The calculator can be used for basic mathematical computation. The calculator has a memory that caches the last result until it is reset. The cached result is used in the next computation if not reset.

The reset is used to clear the cache

Examples will be shown below

Sample Code

from calculator import Calculator

my_cal = Calculator()

Addition

sum method accepts list, int, float

>>> my_cal.sum(10, 2)
12
>>> my_cal.sum(2)
14
>>> my_cal.sum([10, 12.90, 14, 5, 7])
62.9

Because the calculator memory wasn't reset, 2 was added to the result of 10+2. The result 14 was added to list

>>> my_cal.reset
>>> my_cal.sum(3, 2)
5

Subtraction

subtract

>>> my_cal.subtract(5)
-5
>>> my_cal.reset
>>> my_cal.subtract(10, 4)
6
>>> my_cal.subtract(2)
4
>>> my_cal.subtract(3, 1)
0

Multiply

>>> val = [2, 4, 5, 2, 1]
>>> my_cal.multiply(1000)
1000
>>> my_cal.multiply(val)
80
>>> my_cal.multiply(12, 2)
24
>>> my_cal.subtract(4)
20

Division

For divide, zero division returns err

>>> my_cal.divide(100, 5)
20
>>> my_cal.sum(10)
30
>>> my_cal.divide(2)
15
>>> my_cal.divide(0)
err
>>> my_cal.divide(0, 78)
0

Average

average method accepts LIST of int and float to return the computed average

>>> grade = [62, 78.9, 35.78, 90.23, 89.12, 45.78]
>>> avg_grade = my_cal.average(grade)
>>> avg_grade
66.96833333333335

Adding or subtracting without reseting, will add/subtract the value from the last result

>>> my_cal.sum(10)
76.96833333333335

Modulo

For modulo, zero division returns err

>>> my_cal.modulo(10, 2)
0
>>> my_cal.modulo(15, 4)
3
>>> my_cal.modulo(10, 0)
err
>>> my_cal.modulo(14.67, 3)
2.67

Root

>>> my_cal.root(27, 3)
3
>>> my_cal.root(32, 5)
2

Power

>>> my_cal.power(5, 3)
125
>>> my_cal.power(3.5, 3)
42.875
>>> my_cal.power(2, 5)
32
