Example below demonstrates working of bigdecimal class signum method. Method return type is int therefore method returns integers. This bigdecimal class signum method generates, sign of the bigdecimal object value. After analyzing, method returns only one integer among these three integers -1, 0, +1.
For example if the bigdecimal value is negative, method will return -1 as sign for this.object value . If the bigdecimal value is zero, method will return zero as sign for this.object value and if the bigdecimal value is positive, method will return +1 as the sign for this.object value. On the bases of above illustration, it is clear that for any integer or decimal bigdecimal value, method result will be among the these three integers -1, 0 , +1 only.
Method generates NumberFormatException, if it finds the bigdecimal value other than integers and double types values.
Syntax for using the method: public int
BigDecimal obj = new BigDecimal(integer);
int i = obj.signum();
