PLSQL | SIN Function

The PLSQL SIN function is used to return the sine of a numeric value. The SIN function accepts one parameter which is the number whose sine needs to be calculated. The SIN function returns a value of the numeric data type.

This function takes as an argument any numeric data type as well as any non-numeric data type that can be implicitly converted to a numeric data type. If in any case, the argument is BINARY_FLOAT, then the SIN function returns BINARY_DOUBLE.

Syntax:

SIN(number)

Parameters Used:

number – It is used to specify the number whose sine needs to be calculated.

Return Value:
The SIN function in PLSQL returns a numeric value.

Supported Versions of Oracle/PLSQL:

1. Oracle 12c
2. Oracle 11g
3. Oracle 10g
4. Oracle 9i
5. Oracle 8i

Example-1: Using positive numeric value as an argument in the SIN function.

DECLARE 
   Test_Number1 number := 0.5;
   
BEGIN 
   dbms_output.put_line(SIN(Test_Number1)); 
   
END; 

Output:

0.4794255386042030002732879352155713880819 

Example-2: Using 0 value as an argument in the SIN function.

DECLARE 
   Test_Number1 number := 0;
   
BEGIN 
   dbms_output.put_line(SIN(Test_Number1)); 
   
END; 

Output:

0 

Example-3: Using 1 value as an argument in the SIN function.

DECLARE 
   Test_Number1 number := 1;
   
BEGIN 
   dbms_output.put_line(SIN(Test_Number1)); 
   
END; 

Output:

0.8414709848078965066525023216302989996233 

Example-4: Using a negative value as an argument in the SIN function.

DECLARE 
   Test_Number1 number := -5;
   
BEGIN 
   dbms_output.put_line(SIN(Test_Number1)); 
   
END; 

Output:

0.9589242746631384688931544061559939733579 

Example-5: Using SIN function with select query and returning the value in degrees.

select (SIN(5)) * 57.29  FROM dual; 

Output:

-54.9367716954512 

Using the conversion formula of 1 radian = 57.29 degrees.

Advantages:
The SIN function accepts any numeric datatype as well as any non-numeric datatype as an argument that can be implicitly converted to a numeric datatype.
