Hi,
I want to make a phase inverse and didn't find a component to do that so I started to calculate with
x=-x;
but that didn't work. Then I tried
x=-2*x;
and that didn't work either. Then I did
x=x-x-x;
and that works.
Is there a better way to do a phase inverse? I'm sure I'm missing a few things here ... 😮 😉
Best wishes, FRitz

x = 0 - x;

Thanx Stefan!

I have no clue what you are talking about, but wouldn't
x = x * (-1) be more appropriate?

A multiplication is more expensive than a subtraction though 🙂 And it'll give you the same result in this specific case.
skOre ·
Yeah, in this case sure 🙂

Is this true when ussing SSE calculations as well (multiplication more costly tha addition)?
Just thinking for optimisation purposes?
stefan ·
Well, yes in most cases.

Ahh, excellent, thats good to know.. Thanks
I suppose I can always check using the assembler view output of the code component..
