Purpose
Returns a value that is the hyperbolic cosine of the specified arithmetic value.
Parameters
x is a floating-point value.
Examples
COSH(0.0) /* returns 1.0 */
Restrictions
A COSH operation on floating-point decimal data is actually performed using the floating-point binary operation. Thus, the range of the operands and the result of the operation are limited to the ranges for floating-point binary numbers.
Description
The COSH function returns a value that is the hyperbolic cosine of the angle x expressed in radians.
The result has the same data type as x such that COSH(x) ≥ 1.
