Is it bad for optimization? (real instead of integer)

imGua

I have just realized, that in most field where I need to use integer, I'm using real. Is it bad for optimization, and if yes, then how bad it is?

TSB how dare you!
Just like chocolate cake: EVERY byte matters!

@shmuley95 … ) … made my day!

@ImGus … the numerical attribute types set the form of the number when stored … therefore the type you chose allocates a bit/byte allotment for that attribute

Index would need the least bits/bytes as it stores whole numbers; positive
Real would need the most bits/bytes as it stores whole and/or decimal numbers; positive or negative
Integer is in between in bits/bytes allotment as it stores whole numbers; positive or negative

EX: if you only need whole positive numbers: use Index type
if it is possible that your number could be fractional (decimal): use Real
if it is possible that your whole number could be negative: use Integer

any mathematical operation/function can be done on any number no matter what type you have assigned to the attribute.
you can subtract a real number from an integer or index attribute … but, the computer will round-off the number when it stores/displays.

PS of course as TSB says: "but the difference is so small i don't think it will matter."
