hoan why??? [1] // Problem 1214. Strange Procedure 15 Nov 2010 21:55

I got AC, but i dont understand why my code is correct,
in the other word in lines:
" y = sqrt(x+(y/labs(y))*(-labs(y)));"

sqrt(x+(y/labs(y)) > 0
(-labs(y))) < 0

but why when i compile this code y is positive !!!
sorry for my poor english.

y = sqrt[x+(y/labs{y})*(-labs{y})]
so (y/labs{y})*(-labs{y}) < 0 but x + (y/labs{y})*(-labs{y}) > 0
