# SINH macro

The `SINH` macro is available only in Unica Campaign.

## Syntax

`SINH(data [, units_keyword])`

## Parameters

`data`

The numerical values to compute the hyperbolic sine 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 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 Unica Campaign, see Format Specifications.

## Description

`SINH` calculates the hyperbolic sine of the values in the specified data range. It returns one new column for each input column, each containing the hyperbolic sine of numbers in the corresponding input column. For x in radians, the hyperbolic sine of a number is:

where e is the natural number, 2.7182818.

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

## Examples

 `TEMP = SINH(1)` or ```TEMP = SINH(1, 0)``` or `TEMP = SINH(1, RADIAN)` Creates a new column named `TEMP` containing the value `1.18`. `TEMP = SINH(V1)` Creates a new column named `TEMP`, where each value is the hyperbolic sine (in radians) of the contents of column `V1`. `TEMP = SINH(V1:V3, 1)` or ```TEMP = SINH(V1:V3, DEGREE)``` Creates three new columns named `TEMP`, `VX`, and `VY`. The values in the `TEMP` column are the hyperbolic sines of the contents of column `V1`, the values of the `VX` column are the hyperbolic sines of the contents of column `V2`, and the values of the `VY` column are the hyperbolic sines of the contents of column `V3`. All values are in degrees. `TEMP = SINH(V1[10:50]:V2)` Creates two new columns named `TEMP` and `VX`, each with values in rows 1-41 (the other cells are empty). The values in column `TEMP` are the hyperbolic sines of the values in rows 10-50 of column `V1`, and the values in column `VX` are the hyperbolic sines of the values in rows 10-50 of column `V2`. All values are in radians.
