h2. Name

*div* --- Divide a constant value into a dataset or divide a dataset by another

h2. Syntax
{panel:|borderStyle=solid|borderWidth=1|bgColor=#ffffaa}
*div hi* _hiname_ ;# divide active dataset by workspace _hiname_ dataset, result in _hiname_.

*div lo* _hiname_ ;# divide active dataset by workspace _hiname_ dataset, result in active.

*div* _value_ ;# divide _value_ into active dataset, result in active data.

*div x | y | sca* _value_ ;# divide _value_ into x or y or scalar coordinates.

*div x | y | z | sca* \[_value_] *xx | yy | zz | sca* \[_factor_] ;# divide data coordinates by each other.

h2. Description

The *div* command will divide a constant value with a dataset or divide two datasets by each other. *div* works on grid and polydata type of dataset. The result dataset is changed. Dividing by zero will be bypassed. 

    * *Grid*: The two datasets must have the same grid dimensions.
    * *Polydata*: The two datasets must have the same number of points. For polydata the target for the divide operation can be any of the xyz coordinates and scalar values.
    * *Dividing a datasets by another: The dataset in active is divided by the dataset in hiname. The result data is placed in active if the *lo* argument is used, and in the workspace _hiname_ if the *hi* argument is used.

 The command Function !att:_img_icon^calculator.png! is an alternative for mathematical operations on single datasets. Look inside the Geocap Toolbox for commands.

h2. Arguments

*hi* _hiname_
{indent}Divide dataset in active and _hiname_ and the result data will be placed in workspace _hiname_. 
{indent}

*lo* _hiname_
{indent}Divide dataset in active and _hiname_ and the result data will be placed in active workspace. 
{indent}

_value_
{indent}Add _value_ and result data will be placed in the active workspace. 
{indent}

*hi* | *lo* _hiname_ *tes*
{indent}Add two poly dataset together according to rules above and optionally test using the *tes* argument if xy coordinates are equal and then divide only for equal coordinates. 
{indent}

*x* | *y* | *sca* _value_
{indent}Divide value to x- or y- or scalar coordinates. The result data will be placed in the active workspace. 
{indent}
*x* | *y* | *z* | *sca* \[_value_\] *xx* | *yy* | *zz* \[_factor_\]
{indent}Divide _value_ to x or y or scalar coordinates. The result data will be placed in the active workspace. Divide data coordinate axes by each other. Optionally use a value that will be divided by the coordinates and/or a _factor_ that will be divided with the coordinates. *x* | *y* | *z* | *sca* represents the first data coordinates and *xx* | *yy* | *zz* represents the second data coordinates. The result is always placed in the first coordinates.

h2. Examples

h3. Ex.1: Divide a dataset with another

{noformat:|borderWidth=1|bgColor=#eeeeee}
        # Divide a grid in active with a grid in workspace named mygrid and place the result in active
        div lo mygrid
{noformat}

h3. Ex.2: Divide a dataset with a value
{noformat:|borderWidth=1|bgColor=#eeeeee}
        # Divide the value 15 with a dataset in active
        div 15
{noformat}

h3. Ex.3: Divide coordinates
{noformat:|borderWidth=1|bgColor=#eeeeee}
        # Divide x by y data coordinates and place the result in x data coordinates.
        div x yy
{noformat}
