LOG2
Syntax
LOG2(data)
Parameters
data
The numerical values to compute the base2 logarithm 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 IBM® Unica® product.
Description
LOG2 calculates the base-2 logarithm of values in the specified data range. It returns one new column for each input column, each containing the base2 logarithm of numbers in the corresponding input column.
*
Examples
Creates a new column named TEMP containing the value three.
Creates a new column named TEMP, where each value is the base2 log of the contents of column V1.
Creates three new columns named TEMP, VX, and VY. The values in the TEMP column are the base2 logs of the contents of column V1, the values of the VX column are the base2 logs of the contents of column V2, and the values of the VY column are the base2 logs of the contents of column V3.
Creates a new column named TEMP, where the first 11 cells contain the base-2 logs of the values in rows 10-20 of column V1. The other cells in TEMP are empty.
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 base-2 logs of the corresponding rows of column V1, and the values in column VX are the base-2 logs of the corresponding rows of column V2.
