Coding : Which way uses less performance ?

[max-td]

Hi,

i have to understand some basic coding things -
please tell me - if i realize something like this :


if
(ElliotOscillator(Fast, Slow)[0] > a_Level )

{
BackColor = Color.Firebrick;
}

if
(ElliotOscillator(Fast, Slow)[0] < - a_Level )

{
BackColor = Color.Firebrick;
}


Is it usefull to replace the 2-times ((ElliotOscillator(Fast, Slow)[0] ) with for example
double EOvalue = (ElliotOscillator(Fast, Slow)[0];
and use the EOvalue instead of the full term (ElliotOscillator(Fast, Slow)[0]) ?
Or is it the same in performance usage.

ThanX for an info

It is more efficient to hold the value in a local variable than to call the method multiple times.

OK,

would you recommend the way with a local variable also for terms like this ?

if (x == true && y == true)
{ .....

this would be maybe like

bool cond1 = x == true && y == true

+ then
if (cond1 )
{ .....

No, that's redundant.
