''''Entropy''' is a programming language about giving up control. All data decays as the program runs: each value alters slightly every time it's used, becoming less precise. An Entropy programmer needs to abandon the pursuit of precision which most programming demands&mdash;often working against years of habit&mdash;in order to program effectively. Any output from an Entropy program will be approximate, and the more the data is accessed, the more random it will become. The programmer has, at best, a short window to get his/her idea across before the program corrodes. The program itself is not altered&mdash;so the next time it runs, it is restored to its original condition, only to decay again through its next run. Entropy was designed by [[User:Rottytooth]]. ==Inspiration== Entropy addresses the compulsive thinking reinforced by programming, the rigidity of logic, and the way we must compromise with the computer in order to get it to understand us. It is something that has become more familiar to non-programmers as people manage more of their social interactions and other messy human stuff through computers. It was inspired by the [http://www.worldpicturejournal.com/WP_6/Manon.html glitch aesthetic] as used by net.artists such as [http://wwwwwwwww.jodi.org JODI] and by esolangs in the tradition of [[brainfuck]], which twist logic into delicious nonsense. ==Datatypes== All datatypes in Entropy are built on reals (floats). ===real=== A floating point number, which changes slightly every time it's read from. There is no way to compare whether two values are equal, since the values are so unstable&mdash;only the greater than and less than comparisons are available. ===char=== Built on a real, a char rounds off the current value of the real it is built on, and returns the corresponding character. ===string=== An array of chars. ==Examples== ===Hello, world!=== Program MyNamespace MyProgram [ print "Hello, World"; ] This program will print a slight variation on "Hello, World" each time it's run. Such as: Hello+ World or Hellp, World etc. ===99 Bottles=== Program Rottytooth NinetyNineBottles [ declare count real; let count = 99; while count > 0 [ if count < 99 [ print count; print " bottles of beer on the wall.\n"; ] print count; print " bottles of beer on the wall, "; print count; print " bottles of beer.\nTake one down, pass it around, "; let count = count - 1; ] print " no more bottles of beer on the wall."; ] Beginning of output: 98.99005 bottles of beer on the wall, 98.86667 bottles of beer.

Her behavior seemed drunken, and so she was renamed Drunk Eliza. The [http://danieltemkin.com/DrunkEliza web version of Drunk Eliza] uses a mix of C# and Entropy, with all data stored in Entropy datatypes.
