#85828 - Pure Logic
Responding to: ???'s previous message
My understanding is that a function is "pure" if it always returns the same result for the same parameters and has no side effects.

An example might be a square root function.

The fact that a function is known to be pure can by used by a compiler to perform certain optimisations.

By implication, a pure function will be re-enterant because it cannot make use of any global or static local variables.
