RomanAlphabet 1.4

Installation

$ pip install RomanAlphabet

Usage

To represent an integer value into roman numeral system;

: from romanalphabet.romanalphabet import RomanAlphabet
: rr = RomanAlphabet("4785")
: rr.convert_to_roman()
: 'MMMMDCCLXXXV'

or into binary;

...
: rr.convert_to_binary()
: '1001010110001'

numbers can also be added or mutiplied into one another, as following; result could be three type of numeric format; “decimal”, “binary” or in “roman”;

: RomanAlphabet.addition("roman",1)
: 'I'
: RomanAlphabet.multiply("roman",1,2,3)
: 'VI'
: RomanAlphabet.multiply("decimal",1,2,3)
: 6
: RomanAlphabet.addition("binary",1,2,3)
: '110'
: RomanAlphabet.multiply("decimal",7,4,2,4,2,3)
: '10101000000'

If first argument not one of <code>decimal</code> <code>roman</code> <code>binary</code> then the following error will be displayed

: RomanAlphabet.multiply("deciaml",7,4,2,4,2,3)

InvalidInputError: first input must be one of 'decimal', 'binary' or 'roman'

Also roman numbers can be an input and represented with integer and binary format. If anything will goes wrong then for input as an example, none roman numerics if given then an understandable error will displayed.
