rithmetic 0.0.13

Simple arithmetic lib for students

_rithmetic_

“rithmetic” is a budding python package which aims to provide arithmetic and math assistance to students using python to build math related functionality or apps.

How to Install:

Run the following command in Terminal/CLI –

• pip install rithmetic

After installation completes, run the following command in Terminal/CLI to see the welcome message –

• rith

To check for the version of rithmetic run the following command in Terminal/CLI –

• rith-version

License and terms of use:

rithmetic comes with the MIT license which means that anyone, anywhere can use it for any open source or even closed source application.

Current functionality:

1. Convert a positive integer from one base to another (Converters)
2. Check/Verify if a positive integer is from a specified base (Verifiers)

Best way to import:

Import all the functions from rithmetic at once

from rithmetic import *

Functions:

Converters

base(num, fromB, toB)

Converts any positive integer from one base to another. (supported bases are base-2 to base-16)

num – any positive integer | can be both int and str type

fromB – base of ‘num’ | can be both int and str type

toB – ‘num’ gets converted to this base | can be both int and str type

Returns – The converted Integer OR ‘Invalid number’ OR ‘Invalid base value’

Example:

from rithmetic import *

number = base(1111,2,16)
print(number)

This will print ‘F’. As 1111 which is a binary number gets converted to F in hexadecimal.

dectosub(num, toB)

Converts any positive integer from Decimal to any other sub-decimal base. (supported bases are base-2 to base-9)

num – any positive integer | can be both int and str type

toB – ‘num’ gets converted to this base | can be both int and str type

Returns – The converted Integer OR ‘Invalid number’ OR ‘Invalid base value’

Example:

from rithmetic import *

number = dectosub(23,5)
print(number)

This will print 43. As 23 which is a decimal number gets converted to 43 in base-5.

subtodec(num, fromB)

Converts any positive integer from any sub-decimal base to Decimal. (supported bases are base-2 to base-9)

num – any positive integer | can be both int and str type

fromB – base of ‘num’ | can be both int and str type

Returns – The converted Integer OR ‘Invalid number’ OR ‘Invalid base value’

Example:

from rithmetic import *

number = subtodec(25,6)
print(number)

This will print 17. As 25 in base-6 gets converted to 17 in decimal.

Quick single parameter converters

dectob16(num)

num – any positive integer | can be both int and str type

Return – The converted Integer OR ‘Invalid number’

• Any base to Decimal

b2todec(num)

b3todec(num)

b4todec(num)

b5todec(num)

b6todec(num)

b7todec(num)

b8todec(num)

b11todec(num)

b12todec(num)

b13todec(num)

b14todec(num)

b15todec(num)

b16todec(num)

num – any positive integer | can be both int and str type

Return – The converted Integer OR ‘Invalid number’

Verifiers

chkbase(num, base)

Checks if a positive integer is from a specified base. (supported bases are base-2 to base-16)

num – any positive integer | can be both int and str type

base – base of ‘num’ to be checked | can be both int and str type

Returns – True OR False OR ‘Invalid base value’ OR 'Invalid number'

Example:

from rithmetic import *

check = chkbase('23F',16)
print(check)

This will print True. As 23F is from base-16.
