Show a specific number of decimals in floating point numbers in Lua language

Question

I started to learn a little about the language Lua and I’m doing some algorithms to practice and one of them I should show in the output of floating point values with 4 decimal places. In C++ I would use cout << fixed << setprecision(4);, I searched a lot and did not find a way in the language Moon.

Answer 1

Uses in a similar way to printf() of the C language:

string.format("%.4f", 25.33333333)

Behold working in the ideone. And in the repl it.. Also put on the Github for future reference.
