A “Hello World!” in mathematical language?

mXparser is a math parser library, so printing just “Hello World” string is to little 🙂 In order to satisfy deep math needs :-), but still keeping simplicity of the “Hello World!” code, I decided to present two equations:

the first one representing “Hello” string and
the second one “World!” string.

The idea is simple, each word can be translated into series of numbers (each one representing ASCII code of a particular letter), converting this numbers into hex string bytes, after strings concatenation, we are getting final hex string, which can be then converted into decimal number. This operation can be inverted, so we can take decimal number, convert it into hex string, partition hex string into hex byte pieces, and finally pickup ASCII letters 🙂 This inversion will be our “mXparser – Hello Word!” code!

Letter	ASCII code – dec	ASCII code – hex
H	72	48
e	101	65
l	108	6C
l	108	6C
o	111	6F

Text = Hello
Hex string = 48656C6C6F
Decimal number = 310939249775
Prime factorization – for more fun 🙂 – of 310939249775 = $$5^2\cdot 7^3\cdot 11^1\cdot 67^1\cdot 49201^1$$

Letter	ASCII code – dec	ASCII code – hex
W	87	57
o	111	6F
r	114	72
l	108	6C
d	100	64
!	33	21

Text = World!
Hex string = 576F726C6421
Decimal number = 96136172692513
Prime factorization – for more fun 🙂 – of 96136172692513 = $$71^1\cdot 218549^1\cdot 6195547^1$$

We have all we need, so lets do this in 5 different languages 🙂 : JAVA, C#, Visual Basic, C++/CLI, F# – all 5 implementations will use the same API provided by mXparser library!

JAVA – using Eclipse Mars 1
C# – using Visual Studio 2015
Visual Basic – using Visual Studio 2015
C++/CLI – using Visual Studio 2015
F# – – using Visual Studio 2015
C# – – using Mono Develop 4.0

Above tutorials present detailed steps, each step documented with a screenshot! Mentioned “Hello World!” tutorials are also available on GitHub Repo.

Enjoy! 🙂
