COS macro

The COS macro is available only in Unica Campaign.

Syntax

COS(data [, units_keyword])

Parameters

data

The numerical values to compute the 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 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

COS calculates the cosine of the values in the specified data range. It returns one new column for each input column, each containing the cosine of numbers in the corresponding input column.

Examples


`TEMP = COS(PI)` or `TEMP = COS(PI, 0)` or `TEMP = COS(PI, RADIAN)` Returns a new column named `TEMP` containing a single value of `-1`.
`TEMP = COS(90, 1)` or `TEMP = COS(90, DEGREE)` Returns a new column named `TEMP` containing a single value of zero.
`TEMP = COS(V1)` or `TEMP = COS(V1, 0)` or `TEMP = COS(V1, RADIAN)` Creates a new column named `TEMP`, where each value is the cosine (in radians) of the contents of column `V1`.
`TEMP = COS(V1:V3, 1)` Creates three new columns named `TEMP`, `VX`, and `VY`. The values in the `TEMP` column are the cosines of the contents of column `V1`, the values of the `VX` column are the cosines of the contents of column `V2`, and the values of the `VY` column are the cosines of the contents of column `V3`. All values are in degrees.
`TEMP = COS(V1[10:20])` Creates a new column named `TEMP`, where the first 11 cells contain the cosines of the values in rows 10-20 of column `V1` (in radians). The other cells in `TEMP` are empty.
`TEMP = COS(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 cosines of the corresponding rows of column `V1`, and the values in column `VX` are the cosines of the corresponding rows of column `V2`. All values are in radians.
