int ALIAS_Ajuste_Square(INTERVAL &U,INTERVAL &W,double *LOW,double *HIGH)This procedure will return:

- -1 if cannot be a solution of the equation
- 1 if new values have been found for
`LOW`and/or`HIGH` - 2 if the sum of the absolute value of the change between the
initial value of
`LOW, HIGH`and their new value is greater than`ALIAS_Seuil_Ajuste`or if this sum is larger than the initial diameter of multiplied by`ALIAS_Seuil_Ajuste_Percent`divided by 100 - 0 otherwise
