Mathics 0.5
Version of implementation Mathics of programming language Wolfram MathematicaA version of Mathics.
Examples:
Hello, World! - Wolfram Mathematica (438):
Evaluation of this expression results in a string “Hello, World!” itself; since it is not followed by a semicolon, it will be printed as a separate Out
, which is not always convenient.
"Hello, World!"
Hello, World! - Wolfram Mathematica (439):
Print
function outputs its argument(s) to the main output stream. Streams can nest, so for convenience it’s recommended to to use a single stream for all output throughout the program.
Print["Hello, World!"];
Factorial - Wolfram Mathematica (440):
This example uses built-in factorial function !
.
Do
is one of the ways to run a loop — it evaluates its first argument for a sequence of numbers defined by the second argument. In this case it’s all values of i
from 0 to 16, inclusive, with step of 1.
Do[Print[i, "! = ", i!] , {i, 0, 16, 1}]
Fibonacci numbers - Wolfram Mathematica (442):
Print
always outputs a newline after the output, so to prints the numbers in a single line, one has to accumulate them into a string and print it. <>
is concatenation operator, it works only on strings, so the result of Fibonacci
call must be converted to string explicitly using ToString
function.
msg = "";
Do[msg = msg <> ToString[Fibonacci[i]] <> ", " , {i, 16} ];
Print[msg, "..."];
Fibonacci numbers - Wolfram Mathematica (482):
This example uses Riffle
function which in this case alternates elements of the array containing Fibonacci numbers and the separator string “,”.
StringJoin[Riffle[Map[ToString, Table[Fibonacci[i], {i,16}]], ", "]] <> "..."
