# digit_converter
A useful tool for digit conversion, applicable in Genetic Algorithms (GA). It transforms a number into a list of digits under any base, for example, `[1, 0, 1, 0, 1, 1, 1, 0] <-> 174`. 🔢
## Abstract
A cool tool for digits converting. It transforms a number to a list and verse vice, such as represent a number by a binary list.
It could be applied in GA.
**Keywords** Converter, Digits
## Classes and Objects
Classes:
```
BaseConverter:
.tonumber(lst), .tolist(num, L)
DigitConverter:
BinaryConverter: subclass of DigitConverter
IntervalConverter
```
Objects:
```
colorConverter: instance of BinaryConverter
unitIntervalConverter: instance of IntervalConverter == IntervalConverter(lb=0, ub=1)
```
## Grammar
Install the lib, by `pip install digit_converter`
### Import
```python
import digit_converter
```
### Basic usage
```pyhon
print('=*= Example 1 =*=')
print(f'color-converter: {colorConverter.tonumber([1,0,1,0,1,1,1,0])}<->{colorConverter.tolist(174)}')
print('=*= Example 2 =*=')
c = BinaryConverter(exponent=3)
d = c.tolist(12.223, L=8)
print(f'binary-converter: {d}<->{c.tonumber(d)}={c.pretty(d)}')
i, f = c.seperate(12.223, L=8)
print(f'integer part: {i}, fractional part: {f}')
print('=*= Example 3 =*=')
c = IntervalConverter(lb=0, ub=10)
d = c.tolist(2.4, L=8)
print(f'[{c.lb},{c.ub}]-converter: {d}<->{c(d)} -> {c.pretty(d)}-th number')
print('=*= Example 4 =*=')
c = DigitConverter(base=16)
d = c.tolist(2.4, L=8)
print(f'16-converter: {d}<->{c(d)}={c.pretty(d)}')
```
OUTPUT::
=*= Example 1 =*=
color-converter: 174<->[1, 0, 1, 0, 1, 1, 1, 0]
=*= Example 2 =*=
binary-converter: [1, 1, 0, 0, 0, 0, 1, 1]<->12.1875=2^{3} + 2^{2} + 2^{-3} + 2^{-4}
integer part: [1, 1, 0, 0], fractional part: [0, 0, 1, 1]
=*= Example 3 =*=
[0,10]-converter: [0, 0, 1, 1, 1, 1, 0, 1]<->2.3828125 -> 2^{5} + 2^{4} + 2^{3} + 2^{2} + 2^{0}-th number
=*= Example 4 =*=
16-converter: [0, 2, 6, 6, 6, 6, 6, 6]<->2.399999976158142=2*16^{0} + 6*16^{-1} + 6*16^{-2} + 6*16^{-3} + 6*16^{-4} + 6*16^{-5} + 6*16^{-6}
