PLSQL | TANH Function
The PLSQL TANH function is used to return the hyperbolic tangent of a numeric value. The TANH function accepts one parameter which is the number whose hyperbolic tangent needs to be calculated. The TANH 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 TANH function returns BINARY_DOUBLE.
Syntax:
TANH(number)
Parameters Used:
number – It is used to specify the number whose hyperbolic tangent needs to be calculated.
Return Value:
The TANH function in PLSQL returns a numeric value.
Supported Versions of Oracle/PLSQL:
- Oracle 12c
- Oracle 11g
- Oracle 10g
- Oracle 9i
- Oracle 8i
Example-1: Using positive numeric value as an argument in the TANH function.
DECLARE Test_Number1 number := 0.5; BEGIN dbms_output.put_line(TANH(Test_Number1)); END;
Output:
0.462117157260009758502318483643672548721
Example-2: Using 0 value as an argument in the TANH function.
DECLARE Test_Number1 number := 0; BEGIN dbms_output.put_line(TANH(Test_Number1)); END;
Output:
0
Example-3: Using 1 value as an argument in the TANH function.
DECLARE Test_Number1 number := 1; BEGIN dbms_output.put_line(TANH(Test_Number1)); END;
Output:
0.7615941559557648881194582826047935904163
Example-4: Using a negative value as an argument in the TANH function.
DECLARE Test_Number1 number := -5; BEGIN dbms_output.put_line(TANH(Test_Number1)); END;
Output:
-0.999909204262595131210990447534473021089
Example-5: Using TANH function with select query and returning the value in degrees.
select (TANH(5)) * 57.29 FROM dual;
Output:
57.2847983
Using the conversion formula of 1 radian = 57.29 degrees.
Advantages:
The TANH function accepts any numeric datatype as well as any non-numeric datatype as an argument that can be implicitly converted to a numeric datatype.
