The
java.math.BigDecimal.signum() is an inbuilt method in Java that returns the signum function of this BigDecimal. The sign function or signum function is an odd mathematical function that extracts the sign of a real number. In mathematical expressions, the sign function is often represented as sgn.
Syntax:
public int signum()
Parameters: This method does not accepts any parameter.
Return value: This method can return three types of values:
- -1 if this BigDecimal < 0
- 0 if this BigDecimal = 0
- 1 if this BigDecimal is > 0
Below program illustrates the working of the above mentioned method:
Program 1:
Output:
Signum function on 12743 is 1
Signum function on 0 is 0
Signum function on -4512 is -1
Program 2:
