what about square root? Can I do x[i]=sqrt(x[i]*x[i]); ? With math.h at the top of course..Thanks..

x[i] = sqrt(x[i]); otherwise you will get abs(x[i]) ;-)

hehe actually i wanted to get the absolute value..was just wondering if such multiplication is right. ;) THANKS!

esther 2010-09-07 15:37:16

If you want abs, use the abs function. Or multiply by -1 if needed ;-)
