COSH macro

The COSH macro is available only in HCL® Campaign.

Syntax

COSH(data [, units_keyword])

Parameters

data

The numerical values to compute the hyperbolic cosine of. This can be a constant value, a column, a cell range, or an expression evaluating to any of the above. For the format definition of data, see the "Macro Function Parameters" section in the chapter in this guide for your HCL product.

units_keyword

This optional keyword determines whether the input values and results are interpreted as degrees or radians. Select one of the following:

RADIAN - Performs the calculations in radians (default)

DEGREE - Performs the calculations in degrees

If this parameter is not specified, the default is radians. (To convert from radians to degrees, divide by PI and multiply by 180.)

For more details on using keywords in HCL Campaign, see Format Specifications.

Description

COSH calculates the hyperbolic cosine of the values in the specified data range. For x in radians, the hyperbolic cosine of a number is:

where eis the natural number, 2.7182818. COSH returns one new column for each input column, each containing the hyperbolic cosine of numbers in the corresponding input column.

Note: If the value x is too large, an overflow error is returned. This occurs if cosh (x) exceeds the maximum 32-bit floating-point value.

Examples


`TEMP = COSH(0)` or `TEMP = COSH(0, 0)` or `TEMP = COSH(0, RADIAN)` Returns a new column named `TEMP` containing the value one.
`TEMP = COSH(V1)` Creates a new column named `TEMP`, where each value is the hyperbolic cosine (in radians) of the contents of column `V1`.
`TEMP = COSH(V1:V3, 1)` or `TEMP = COSH(V1:V3, DEGREE)` Creates three new columns named `TEMP`, `VX`, and `VY`. The values in the `TEMP` column are the hyperbolic cosines of the contents of column `V1`, the values of the `VX` column are the hyperbolic cosines of the contents of column `V2`, and the values of the `VY` column are the hyperbolic cosines of the contents of column `V3`. All values are in degrees.
`TEMP = COSH(V1[10:20])` Creates a new column named `TEMP`, where the first 11 cells contain the hyperbolic cosines of the values in rows 10-20 of column `V1` (in radians). The other cells in `TEMP` are empty.
`TEMP = COSH(V1[1:5]:V2)` Creates two new columns named `TEMP` and `VX`, each with values in rows 1-5 (the other cells are empty). The values in column `TEMP` are the hyperbolic cosines of the corresponding rows of column `V1`, and the values in column `VX` are the hyperbolic cosines of the corresponding rows of column `V2`. All values are in radians.
