There would only be a performance difference in a compiled language, because it would compile the program differently by hardcoding that value into the software so it doesn't have to query a memory address each time it wants that value.
LOL good one. Again I bring up the "Racoon knows nothing about programming" comment. If the constant is not stored in memory, then pray tell where is it stored? A computer has two storage locations, memory and registers. You would never store a constant in a register because registers are used for arithmetic, and you can't perform arithmetic (changes a value) on something that's value can't be changed. Stop making up stuff when you don't know a damn thing about what you are saying. A CONSTANT IS STORED IN MEMORY.
