digit_converter 2.3

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.

Basic usage

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)}')
