Purpose

COSH returns the hyperbolic cosine of n.

This function takes as an argument any numeric datatype or any nonnumeric datatype that can be implicitly converted to a numeric datatype. If the argument is BINARY_FLOAT, then the function returns BINARY_DOUBLE. Otherwise the function returns the same numeric datatype as the argument.

Examples

The following example returns the hyperbolic cosine of zero:

SELECT COSH(0) "Hyperbolic cosine of 0" FROM DUAL;
