TANH is one of the vital Numeric/Math functions of Oracle. It is used to get the hyperbolic tangent of a number. The TANH function is supported in the various versions of the Oracle/PLSQL, including, Oracle 12c, Oracle 11g, Oracle 10g, Oracle 9i and Oracle 8i.
Syntax:
TANH ( number )
Parameters:
number: It is used to specify the number to get the hyperbolic tangent value of.
Example 1:
TANH (1) |
Output:
0.76159415595576
Explanation:
The hyperbolic tangent value of 1 is 0.76159415595576, and so is the result.
Example 2:
TANH (-1) |
Output:
-0.76159415595576
Explanation:
The hyperbolic tangent value of -1 is -0.76159415595576, and so is the result.
Example 3:
TANH (0) |
Output:
0
Explanation:
The hyperbolic tangent value of 0 is 0, and so is the result.
