# LT macro

The `LT`

macro
is available in Unica Campaign and Unica Interact.

## Syntax

`data1 LT data2 data1 < data2`

## Parameters

`data1`

The
numerical cell range to compare. 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.

`data2`

The number(s) to compare
all values in the specified column against. 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

`LT`

compares
the two specified data ranges, returning a one if the values in the
first data set are less than the values in the second data set or
a zero otherwise. It returns a new column for each input column, each
containing the corresponding column in `data1`

compared
to the corresponding column of `data2`

(that is, the
first column of `data1`

is compared to the first column
of `data`

, the second column with the second column,
and so on).

If `data2`

is a constant, each value
in `data`

is compared to that value. If `data2`

is
a column, the calculations are performed on a row-by-row basis. The
values in `data1`

are compared to the first row value
of `data2`

, the second row with the second row, and
so on. This row-by-row calculation produces a result for each row
up to the last value of the shortest column.

`LT`

operator
can be abbreviated with a less than sign (`<`

).## Examples

`TEMP = 3 LT 4` or `TEMP = 3 < 4`
Creates a new column named |

`TEMP = V1 < 8` Creates
a new column named |

`TEMP = V1:V3 < 2` Creates
three new columns named |

`TEMP = V1 < V1` Creates
a new column named |

`TEMP = V1 < V2` Creates
a new column named |

`TEMP = V1[10:20] < V2` or ```
TEMP
= V1[10:20] < V2[1:11]
``` Creates
a new column named |
