Question

Answer 1

+13 A:

Maybe I'm missing something:

abc = -abc;

If you want it to be negative whether it was negative beforehand or not, you would use:

abc = -Math.Abs(abc);

That's how I read the question, too.

Skeet's gravitational pull is so massive he just attracts points. Eventually he will be crushed by their weight into a singularity, at which point we'll be sucked through the event horizon and Jeff will poke his eyes out and scare the bejesus out of everybody.

@Will: Do you mean Jeff will poke *my* eyes out, or his own?

Jon Skeet 2010-05-24 12:38:24

you mean it's forming a black hole that has already become a neutron star ? beware Jeff..

@Jon no I mean Jeff will play Sam Neil's role (my comment isn't very funny but its less so if you don't get the reference: http://www.imdb.com/title/tt0119081/)

Answer 2

+4 A:

This is how you can convert your int value to minus in c#

abc = abc > 0 ? abc*(-1) : abc;

Answer 3

+1 A:

how about....

xyz = xyz * (-1)

Bhaskar 2010-05-24 12:35:53

what if xyz is already negative ?

this. __curious_geek 2010-05-24 12:37:30

I agree....in that case we would need to do an Abs on that number, i.e. xyz = Math.Abs(xyz) * (-1). Thanks for pointing out....
