ASCII Conversions

  • Functions and their uses

ASCII

Conversions from ASCII to:
  • base2
  • base16

Author: Ian Doarn

pygorithm.binary.ascii.to_base16(string, visualize=False)[source]

Convert ascii to hexadecimal :param string: string to convert :param visualize: Show process :param as_string: return value as string not array :return: hex representation of given string

pygorithm.binary.ascii.to_base2(string, visualize=False, as_string=False)[source]

Convert ascii string to binary :param string: Ascii string :param visualize: Show process :param as_string: join strings with a space as one large value :return: array of binary numbers, or entire string

Base2 Coversions

  • Functions and their uses

Binary: Base2

Conversions from base2 to:
  • base10
  • base16
  • ASCII

Author: Ian Doarn

pygorithm.binary.base2.to_ascii(b, visualize=False)[source]

Convert binary to ASCII

Parameters:
  • b – binary number or array
  • visualize – Show process
Returns:

ASCII String
pygorithm.binary.base2.to_base10(n, visualize=False)[source]

Convert given number to a list for every number do the following formula

x * 2 + number

repeat for each result! Example:

binary number = 100110

0 x 2 + 1 = 1 1 x 2 + 0 = 2 2 x 2 + 0 = 4 4 x 2 + 1 = 9 9 x 2 + 1 = 19 19 x 2 + 0 = 38

Parameters:
  • n – binary number
  • visualize – Show process
Returns:

decimal number
pygorithm.binary.base2.to_base16(n, visualize=False)[source]

Convert binary numbers to hexadecimal numbers

Parameters:
  • n – binary number
  • visualize – Visualise the process
Returns:

hexadecimal number

Base10 Coversions

  • Functions and their uses

Binary: Base10

Conversions from base10 to:
  • base2
  • base16

Author: Ian Doarn

pygorithm.binary.base10.to_base2(n, visualize=False)[source]

Divide each number by 2 using the % operator.

Reverse the resulting list of numbers and return the result

Parameters:
  • n – decimal number
  • visualize – Show process
Returns:

binary number
pygorithm.binary.base10.to_base16(n, visualize=False)[source]

Convert decimal number to hexadecimal

Divide the number by 16 and add the remainder to a list, round down the value after division and repeat till our value is 0

Reverse the results list, get each values respective hex value using HEX_VALUES map

Parameters:
  • n – decimal number
  • visualize – Show process
Returns:

hexadecimal number

Base16 Coversions

  • Functions and their uses

Binary: Base16

Conversions from base16 to:
  • base2
  • base10
  • ASCII

Author: Ian Doarn

pygorithm.binary.base16.to_base2(h, visualize=False)[source]

Convert hexadecimal to binary number

Parameters:
  • h – hexadecimal number
  • visualize – Show process
Returns:

binary number
pygorithm.binary.base16.to_base10(h, visualize=False)[source]

Convert hexadecimal number to decimal number

Send hex to a list and reverse. Evaluate each hex value via HEX_LETTER_VALUES map. Enumerate the list,

using the equation: value * 16 ^ index

value is the hex char value: F -> 15 index is its position in the list: [‘1’, ‘A’, ‘F’] F’s index = 2

Continue this for each hex letter until we reach the end of the list, summing all evaluated values.

Parameters:
  • h – hexadecimal number
  • visualize – Show process
Returns:

decimal number
pygorithm.binary.base16.to_ascii(h_array, visualize=False)[source]

Convert base16 array to ASCII string

Input must be a list of strings: Example:

array = [
‘74’, ‘68’, ‘65’, ‘20’, ‘71’, ‘75’, ‘69’, ‘63’, ‘6B’, ‘20’, ‘62’, ‘72’, ‘6F’, ‘77’, ‘6E’, ‘20’, ‘66’, ‘6F’, ‘78’, ‘20’, ‘6A’, ‘75’, ‘6D’, ‘70’, ‘73’, ‘20’, ‘6F’, ‘76’, ‘65’, ‘72’, ‘20’, ‘74’, ‘68’, ‘65’, ‘20’, ‘6C’, ‘61’, ‘7A’, ‘79’, ‘20’, ‘64’, ‘6F’, ‘67’

]

result -> the quick brown fox jumps over the lazy dog

Parameters:
  • h_array – hex value array
  • visualize – Show process
Returns:

ASCII string
