A module to represent numbers by their place value.

Project description

NumRep

https://travis-ci.org/necessary129/NumRep.svg

Version: 0.1.3

This module provides a way to represent the place values in a given number, eg:
>>> a = NumRep(1234456789123)
>>> a
NumRep(Crores=123445,Lakhs=67,Thousands=89,Hundreds=1,Tens=2,Ones=3)
>>> a.crores
123445
>>> a.ones
3
>>> a.hundreds
1
>>> a.tens
2
>>> a.lakhs
67
>>> print(a)
123445 Crores, 67 Lakhs, 89 Thousands, 1 Hundred, 2 Tens, 3 Ones
This raises TypeError when you give it an invalid number, eg:
>>> a = NumRep('notanumber1111')
Traceback (most recent call last):
...
TypeError: Not a valid Number.
And Every integer in the NumRep has a GetRep() method, which returns the Representation of the number itself, eg:
>>> a = NumRep(123456789)
>>> a
NumRep(Crores=12,Lakhs=34,Thousands=56,Hundreds=7,Tens=8,Ones=9)
>>> a.crores
12
>>> a.crores.GetRep()
NumRep(Tens=1,Ones=2)
>>> a.crores.GetRep().tens.GetRep()
NumRep(Ones=1)
You can also do arithmetic operations on them and then use GetRep(), eg:
>>> a = NumRep(123456789)
>>> a
NumRep(Crores=12,Lakhs=34,Thousands=56,Hundreds=7,Tens=8,Ones=9)
>>> (a.crores - 2).GetRep()
NumRep(Tens=1)
You can compare and do arithmetic operations NumReps with integers and also with other NumReps, like:
>>> c = NumRep(15)
>>> c
NumRep(Tens=1,Ones=5)
>>> c + 10
NumRep(Tens=2,Ones=5)
>>> b = NumRep(10)
>>> b
NumRep(Tens=1)
>>> c + b
NumRep(Tens=2,Ones=5)
This class also provides an all() function, which gives you the real value of the given denomination, eg:
>>> a = NumRep(1234456789123)
>>> a.all('hundreds')
12344567891
You can also use the values specified in the module for all(), eg:
>>> a = NumRep(1234456789123)
>>> a.all(CRORES)
123445
