[DUG] Curious re efficiency of using in [set of integer]

[Ross Levis]

I did have to do some assignments to a variable and do a test on it to stop optimization.

Hi Rohit,

Could that same operation be affected by any optimisation?

Perhaps change the integer for each of the 10,000 ops.

I'm not sure but I've been caught out before with such things.

Cheers

Gary

Just put it in a loop of 10k and time it. 

But honestly, does it really matter?

Var Total: Integer;

If I want to test 2 or 3 values of an integer, I often use

if Total in [4,6] then ...

But is that more or less efficient for the CPU/ASM coding than

if (Total = 4) or (Total = 6) then ...

I’m not sure how to find out myself.
