To execute a chunk, Lua first precompiles the chunk into instructions for a virtual machine, and then it executes the compiled code with an interpreter for the virtual machine. The third parameter of the load function can be used to set the environment of the generated function and the fourth parameter controls whether the chunk can be in text or binary. In some cases, the approximation will match the number exactly, but in some cases, it will only be an approximation.
