mathMC "is a 3d function plotter in Minecraft. You can easily plot math functions in your MC world. Minecraft is a 3-dimensional world, so it's perfect for 3d functions."
I am happy that mathMC is powered by mXparser 🙂
Using built-in random variable [Uni] from uniform continuous distribution over [0; 1] interval we sample two numbers (x,y) then check if point is inside the circle. Operation is repeated n-times, then proportion falling into circle is being measured. This is only 1/4 of the circle (positive x and positive y) with radius 1, so 4 times proportion should give estimation of pi.
Argument n = new Argument("n = 100000");
Expression e = new Expression("4 * sum(i, 1, n, if( [Uni]^2 + [Uni]^2 <= 1; 1; 0) ) / n", n);
mXparser.consolePrintln("Res. : " + e.getExpressionString() + " = " + e.calculate());
[mXparser-v.3.0.0] Res. : 4 * sum(i, 1, n, if( [Uni]^2 + [Uni]^2 <= 1; 1; 0) ) / n = 3.14748
Recently I found on the internet online calculator powered by mXparser. This is one possible usage scenario of mXparser engine, here only part of functionalities are utilized. (no user defined functions, recursion, only one argument), yet calculator is nice 🙂
Expect mXparser v.3.0.0 release soon 🙂
mXparser – 1000 downloads !
I am happy to announce that first milestone was achieved – as of today mXparser has 1000 unique downloads, and the number is growing! This is very exciting, especially considering questions you asked and feedback I gained. mXparser seems fits your needs providing the same API for JAVA, Android and .NET (including MONO). Single framework / technology days have gone away, and are not coming back, meaning cross-platform apps are with us for good.
mXparser downloads were significantly boosted after launching http://MathParser.org site, amazing! Thank you Google!
