Here's toy language for 32-bit float computations in OCaml.
For example, if you want to compute the n'th harmonic number, you could encode this as:
let harmonic : compiled_fn =
compile {
name ="harmonic";
inputs = ["n"];
body = Sum("i", Num 1.0, Var "n", Div(Num 1.0, Var "i"));
}
Your function gets compiled to native code using LLVM. You can then call 'harmonic' like this:
run harmonic [10.0]
Don't use this compiler in a space vehicle.
Do use it to learn about LLVM.
Cheers,
Alex
