Square adjustment

Assume that an equation is written as $(x-W)^2=U$ where $U,W$ are intervals and $x$ lie in the interval [LOW, HIGH]. According to the interval values LOW and HIGH may not be compatible with the equation. The procedure ALIAS_Ajuste_Square allows one to obtain new bounds for the range for $x$:
int ALIAS_Ajuste_Square(INTERVAL &U,INTERVAL &W,double *LOW,double *HIGH)
This procedure will return:
