SIGN macro

The SIGN macro is available only in Unica Campaign.

Syntax

SIGN(data)

Parameters

data

The numerical values to compute the sign 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.

Description

SIGN tests the sign of the values in the specified data range. It returns one new column for each input column, each containing the sign of numbers in the corresponding input column. Positive one is returned for all values greater than zero; negative one is returned for all values less than zero; zero is returned for values of zero.

Examples

TEMP = SIGN(-3)

Creates a new column named TEMP containing the value -1.
TEMP = SIGN(V1)

Creates a new column named TEMP, where each value is the sign of the contents of column V1.
TEMP = SIGN(V1:V3)

Creates three new columns named TEMP, VX, and VY. The values in the TEMP column are the signs of the contents of column V1, the values of the VX column are the signs of the contents of column V2, and the values of the VY column are the signs of the contents of column V3.
TEMP = SIGN(V1[10:20])

Creates a new column named TEMP, where the first 11 cells contain the signs of the values in rows 10-20 of column V1. The other cells in TEMP are empty.
TEMP = SIGN(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 signs of the values in rows 10-50 of column V1, and the values in column VX are the signs of the values in rows 10-50 of column V2.
